It goes together just like a regular AR. The only thing it does not use the the buffer and recoil spring. I recently put one together using a CMMG barrel and Ciener conversion. With a dedicated barrel you need the barrel collar that replaces the chamber insert on the conversion bolt. I have been using a 22lr AR for training since 2005. Back then I used a Ciener with the chamber insert. That conversion kit had 15K-20K rounds through it before I built a dedicated gun. The dedicated gun was built about a year ago and has to have at least 10K on it now. The only magazines to use with the conversion are the Black Dog magazines. If you do not use the CMMG Evolution kit that has its own bolt hold open setup you need to get the bolt hold open followers for the Black Dog Magazines. 5 Pack Bolt Hold Open Followers What they do is keep the bolt form dropping on an empty chamber. The reason why this is so important is the firing pins are a bit fragile on these and dryfiring can cause the firing pin to break. I had several broken firing pins before using these followers and none since. When you remove the magazine the bolt drops but it prevents you from accidnetally dryfiring the gun. A lot of people talked about having problems from the dirty rimfire. But that was with the cahmber insret conversions because the gas tube was still intact. This dumped additional crud into the receiver. Since I went to a dedicated I can easily fire 1,500-2,000 rounds between cleanings if I am not using my suppressor. With my suppressor I get about 500-1,000 between cleanings. As far as cleanings go you need to remove the firing pin on a regular basis to clean it out. I would say every 5,000 rounds or so because it does get caked with crud enough to cause misfires. One more thing, you might see recomendations of polishing the kit to make them more reliable. I did not do it to my most recent kit and it has been 100% reliable. About the only thing I might do is round the bottom rear of the bolt if you plan on shooting subsonics a lot. Not really sure if it is needed but if you are having issues cycling subsonics this does help. I also do not oil my kit and that seems to help keep it running longer. If I do start having issues and can't clean I normally use WD-40 or my home concoction as a stop gap to keep shooting. My home concoction is 33% ATF + 33% 30 weight synthetic + 33% fuel injector treatment. I mix it in a syringe and use it as needed. One could also mix a quart of ATF and oil then add the treatment. This has some slickness to it and also has a very strong cleaning action. They are not any harder to assemble than a regular AR but they are a whole lot more fun. I shoot my 22 AR 100x more often than my 5.56 AR and with the right ammo they are very accurate. And with a suppressor they are extremely quiet platforms with the exception of the hammer noise . If you have any questions feel free to shoot me a PM and I'll give you my number so you can call me. Dolomite

I just did a test with near max loads of Power Pistol, HS-6 and Clays. None of them were able to produce any results. The results on their page is obviously from ideal conditions. I probably just got scammed. Dolomite

I recently bought some Glow Ammo dots. They are nothing more than stickers with a glow in the dark coating. I think I got screwed but figured and by the time I returned them I would only get back about $10. Because of this I am going to give them an honest evaluation. I am also going to compare them to some regular glow in the dark paint I have. In the instructions it says I need fast burning powder and cites Bullseye as the powder to use. The fastest powder I have on hand is Clays which is a bit slower than the Bullseye. But what got me thinking is if it is the flash that "charges" the dots as they are fired then a powder with a large muzzle flash would be just as good. So is there anyone out there that knows of a 9mm or 45 acp comaptible powder that has a bright muzzle flash? I don't mind buying the powder but if someone local to me, Knoxville area, that has enough Bullseye or other high flash pistol powder for me to load a few dozen rounds I would gladly meet them. I am set in the the pistol powder I use, Power Pistol, so buying a different kind would leave me with more to store. Thanks Dolomite

Rem oil tends to be really thin. CLP is definitely thicker than Rem oil. Rem oil is more like a cutting oil based on the consistency, about the sme as WD-40. CLP is thicker and also has cleaning agents in it. I have started using a 33%/33%/33% mix of fuel injector cleaner, automatic transmission fluid and 30 weight synthetic in the same way one would use CLP. You could probably just add the two quarts together then add the gas treatment and it works just as well. It keeps the carbon loose and broken up. It works especially well on my 22's when they start to have malfunctions from all the crud they seem to get. A few drops and the carbon runs out. It is still pretty slick but has a very strong cleaning action to it. I buy large syringes and load them up that way. I grind the needle down so it isn't sharp and it helps you put it where it should be without a big mess. Best part is you can have a lifetime supply for under $7. Dolomite

+1 Completely slipped my mind as well. Silly rule but a rule none the less. Dolomite

Ok, I got the kit today and I am sending it back. I would consider it a rip-off. It is glow in the dark stickers, nothing more. The light produced by the powder "charges" the glow sticker. The same can be done with stickers bought at Walmart or even glow in the dark paint. For the $28 I paid for 85 stickers I feel ripped off, even a bit dirty for letting myself get screwed this hard by a complete stranger. Dolomite

An AR pistol is just that a pistol. So long as you do not attach a shoulder stock you are perfectly legal regardless of barrel length or caliber. Now once you attach a shoulder stock it must either have a 16" or longer barrel or be registered as a SBR prior to attaching the shoulder stock. It also matters how the receiver was originally registered or transferred. If the lower receiver was ever a "rifle" or assembled as a "rifle" it cannot be turned into a "pistol", period. A "pistol" can be turned into a "rifle" by adding a shoulder stock and 16"+ barrel but a "rifle" cannot have those items removed and become a "pistol". And remember the ATF states "once a rifle, always a rifle". There are a few exceptions to this statement like the TC Contenders but even they need to follow the rules regarding SBR. When they have a barrel less than 16" they must have the pistol grip installed and not the shoulder stock. Also, with an AR I do believe you need to have the pistol buffer tube installed or a buffer tube that will not readily accept a shoulder stock. Just removing the shoulder stock from a rifle buffer tube on a rifle is not good enough. Dolomite

You are going to be amazed then. CLP is a "all-in-one" product that does nothing really well. Grease works really well towards protecting as well as the function of most firearms. Dolomite

I use moly grease on every wear surface on a gun. I buy the grease gun tubes that Walmart sells for under $5. I have taken AR's and added moly grease to the hammer/trigger junction and had people swear the trigger had been worked on. I use it on slide/frame junctions as well as hammer/sear junctions. People say that it seasons the metal, keeping it slick after the grease is gone. I honestly believe this besed on how well it has performed for me. Another great thing about the moly grease I use is it doesn't seem so sticky that it attracts debris. And once you wipe off the excess it rarely oozes out. And that $5 tube is about 1/2 way gone now and I bought it about 3 years ago so it goes a long way. The assembly lube is good but it is designed to break down as it heats up. That way it doesn't gum up and block passages on a new engine. As long as the gun didn;t get too hot it would probably work pretty well. I know because I have spent my entire adult life building cars. Also some assembly lube isn't as slick as others, some of it can be like honey. Dolomite

Not sure about the 77 grain out of a 9 twist but according to the miller formula it can. I have alsor read reports of people shooting them effectively out of a 9 twist. And actually a 9 twist would be a better alternative for short barreled guns intended to shoot the 77 grain bullets. The reason is they are barely stabile but still stabile enough for flight but will tumble readily in soft targets. And this would be great considering the low velocities the 77 grain round starts with. You need every advantage you can with a slow starting velocity and the SMK's that tumble readily do have an advantage over FMJ rounds of any weight. Out of a 16" carbine the velocity of the BH 77 grain load is roughly 2700 fps and at 300 yards it is only 2000 fps. Out of a 14.5" gun the same load is only 2,400 fps at the muzzle and 1,750 at 300 yards. At the extended ranges with a 7 twist barrel the bullet is likely to just pass through because of the reduced velocity and overstabilization. With a 9 twist it will tumble and hopefuly come apart but at a minimum it will at least tumble. If someone wants to test this set some water jugs aup at 100, 200, 300 and 400 yards and fire the 77 grain loads out of a 7 twist gun. I bet at the 300 and 400 yard ranges you are going to see a very small exit hole. Now the same load out of a 9 twist gun will likely tumble at the extended ranges causing more damage. Also, what makes SMK's better than FMJ's is the thin jackets used on SMK's. The thin jackets work as well and often better than SP's. Definitely better than any FMj at an extended range regardless whether the FMJ's tumble or not. What rifle were these wounds made with? 14.5" M4, 16" carbine or the 20" carbine? I think their decision to go with a faster twist was in a quest to turn a short-medium range cartridge into a long range cartridge by using heavier bullets. Some say it was for the NATO tracers but we already had effective tracers in our supply system. Personally I do belive it was an attempt to extend the range of our AR platform beyond the original 300 yards capability. The original incarnation of the AR with its 55 grain bullet and 12 twist barrel was devastating for a couple of factors. First the velocity was very high because of the longer barrels and faster twists. And with the 12 twist barrel the bullet readily tumbled and then fragmented because it was stabile in flight but not in soft tissue. But the original incarnation was a short range cartridge that was designed for engagements under 300 yards. The 55 grain loading left a 20" barrel at roughly 3,200-3,300 fps and fragmented and tumbled upon impact. It was a very devastating round indeed inside of its limitations. People do regularly get hit and survive being hit with a 5.56. When that happens it is because the bullet did not tumble or fragment because the distance was at extended ranges. Most people are going to survive a clean 22 caliber hole so long as it doesn't hit vital blood supplies or CNS. When the bullets fragment or tumble that is where the damage comes from. And when a bullet is overstabilized it will not tumble and if velocity is below the bullet's fragmenting threshold it will just pass through just like a 22lr. Just as you I have seen it first hand. Had a guy we brought in that had been hit in the upper left thigh. He was walking and talking with very little blood. Here is a very good study on the performance of various loads for the 5.56. http://www.texassmallarmsresearch.com/TechInfo/556Performance/556Performance.pdf Note page 4 that M855 bullets do not reliably fragment at velocities below 2,500 fps in a7 twist barrel. And considering out of a M4 (14.5" barrel) the M855 is at 2,900 fps but at 200 yards it is only going 2,400 fps, well below the fragmenting threshold for that round. This means at roughly 150 yards the m855 fired out of a M4 will no longer reliably fragment. Or out of a 16" carbine that range is extended to roughly 200 yards but not much more. All of this is because of the twist rates. The tumbling is what starts the fragmenting process. This is the reason why the Marines are having less issues than the Army. They use 20" rifles that extend that range some because of the extra velocities. Ideally what the military needs to do is go back to the old ay of thinking. Have a 0-300 yard cartridge and a 300+ yard cartridge rather than trying to make the current 0-300 perform duties as a 300+ yard cartridge. There are plenty of calibers out there that would fit the 300+ yard category without much additionl weight that needs to be carried. Look at all the 6mm and 6.5mm calibers that are being used in 1,000 yard competitions. Any one of those would be better than ANY 5.56 loading beyond 300 yards. Again we are talking performance beyond the original 300 yard capability of the 5.56. Dolomite

I just read a lot of the PSA website. They are as good as BCM or alt least say they are. I would not have a problem with PSA stuff based on what I have read. I will say BCM stuff is also very high quality stuff and their customer service is second to none. Dolomite

Considering the ammo you plan on shooting I would choose a 1/9 over a 1/7. Also with the shorter barrel you are not going to get the velocity needed to reach the heavier ammo's full potential. With a 9 twist barrel the bullets are not going to be as overstabilized as with a 7 twist. Overstabilization is what prevents bullets from tumbling and fragmenting upon impact like they were designed to do. You either need the bullet to tumble upon impact so it fragments or you need enough velocity for the bullet to come apart upon impact. Now this can be mitigated with modern ammunition designs but I would be willing to bet 95% of those who have ammo set aside are saving FMJ rounds that are 62 grains or 55 grains. And these are going to work better with a 9 twist than a 7 twist barrel. Most of this has to do with down range performance rather than CQB distances. At longer engagement distances, like we are seeing overseas, the faster twist barrels are overstabilizing the bullets so that when they hit a "soft" target at the lower velocities they do not tumble and fragment. And because the velocities are lower at this point the bullet will not come apart upon impact either. This leads to a 22 lr type wound as the bullet is too overstabilized to tumble and too slow to disrupt the bullet's integrity. The only time I would recommend a 7 twist barrel is when the barrel is long and the person is planning on using heavy bullet pretty much exclusively. The reason is those heavy bullets need the added velocity to work well at any distance beyond probably 100 yards. A short barrel with a 7 twist shooting heavy bullets has got the sorst of all worlds. The barrel is too short to getthe velocity up and the twist is too fast for the bullet to tumble. Another thing ot consider is with a longer barrel in a 7 twist gun you can be limited on how light you can go depending on bullet design. I do know with a 7 twist 53 grain SMK's will come apart from centrifugal force at 3300 fps and 40 grain VMax bullets at about 3400-3500 fps. When looking at stabilizing heavy bullets I will say this. I shoot 69 grain SMK's out of a 16" 9 twist barrel and they are very accurate. So a 9 twist barrel should stabilize anything up to that. None of this really matters unless you realize this rifle may someday be used for something other than the range. I know we are not at war now but you never know when the rifle you build might have to be used in that role. As far as cycling goes a rifle should cycle pretty much anything US made if it is setup correctly and broken in. If a gun is shortstroking using Remington UMC then it has issues other than the ammo. Could be the gas port hole is drilled too small or off a little allowing the gas block to partially block it. Dolomite

When I was in many, many moons ago there was a concern over gangs getting training and access to equipment. Dolomite

I think gels give you the ideal performance of a bullet. Other things such as clothing, walls or glass can negatively affect bullet performance. If someone wanted to test it wouldn't be that had to use a piece of hard wood or get some bones from a local meat processor. Or to make it standard use some sort of polymer that mimics the density of bone. One good thing about hits on bone is they can create secondary missles that can also do damage. Dolomite

California is probably the only place a "there is a 300 pound naked body builder sitting on my porch" call wouldn't be considered a prank call. Dolomite

I also ask to see a HCP or at least a license. If all they have is a license I ask if they can legally possess a firearm. After that it is the same protocal as selling a set of golf clubs. Dolomite

ATF over exaggerates their timelines. They kept telling me mine was going to take a lot longer than the 97 days it actually took. Hopefully with the new process the times will shorten up some. Dolomite

22 AR's are just as addictive, maybe even more so, that regular 5.56 AR's. You can fire them more places and they can be just as accurate not to mention much cheaper to shoot. And with a dedicated 22 you don't have all the reliability issues you do with a conversion kit. The reason is there isn't a constant dumping of crude down the gas tube. I will say that my build using a CMMG barrel is very accurate. Dolomite

I am about 20 minutes east of Knoxville. When you do make it we can shoot here at my house to get the rounds chronographed. You will be surprized at how much of a difference there is. Even between like guns the velocity can be different. Dolomite

You notified the dealer of all the issues the pistol had so your hands have probably been washed. You have to realize that being named in a suit, no matter how frivolous, is going to cost you money. And those who are looking for compensation are going to name as many people as they can just to increase their odds of winning something. Just showing up in court to have it dismissed is going to cost you. In today's litigious society anyone can be sued for anything anymore. All it takes is a sympathetic lawyer who thinks they can win. After the case is dismissed you can go back and collect your legal fees after the fact but the outlay ahead of going to court can be substantial. Either way I am done and welcome back to the forum.

And when mounting a scope make sure it is as far forward in the slots as possible when tightening. This keeps it from moving under recoil. I normally set the weapon on its muzzle to do the tightening of the scope rings. Dolomite

For you to make accurate range cards or get accurate holdover information you need to find what ammo you are going to use and then fire it across a chronograph. In all the factory ammo I have fired across my chronograph none have lived up the advertised numbers. And without the correct velocity you are just guessing at ballistics. The only other way to determine correct holdover is to actually get out and shoot it at various distances. But that information is only good for that area and on that day. It will change with weather conditions such as temperature, humidity and pressure. Also, elevation can have an impact on ballistics as well. But when shooting across a chronograph and getting velocity at 10 feet from the muzzle you can use that number to figure out all the ballistics for all the different areas and conditions you might hunt in. Not sure how often you make it to Knoxville but if you are ever in the area bring your rifle and you can shoot it across my chronograph. Dolomite

Women do not shoot as much as men, fact. Now some women do shoot more than some men but as a whole you see 10X the amount of men at a range than women. Now times are changing and we are seeing more women at the ranges but they are still a rarity. Case and point was this weekend at a range. There was a HCP class being put on and the majority of the attendees were women. When all the men noticed that there were more than three women at the range the men began wondering what was going on. If women were at the range as much as men no one would have noticed. Never said the BG was designed with the women in mind. Just stating that a women is more likely to choose the BG over some of the other platforms. I know because I do help out women regularly with firearms. I have taught, although not lately, plenty to know that the majority of women are going to choose a smaller firearm, like the BG, over a larger gun. Not all women but the majority. Never said women are not as good as men, not going to goat me into that one. As far as being at the range lately, yes I do go a lot. When I am not shooting at home I find myself at local ranges. I generally hit a public range at least once a week and more often than not twice a week. I do shoot a lot and try to pull the trigger on something every single day even if it is only a few magazines. I will say I have observed the same thing as glockster157 said. Most dealers wanting to invest the minimum amount of time and money into used guns. Makes sense business wise to minimize your costs. I have watched dealers take in used guns and sell them without so much as racking the slide. The Sig 380 is a fine weapon. I recommended it to a female friend this week. Easy to rack and small which seems ot fit a lot of women's needs. Dolomite

I use several differnt kinds of primer tools dependong on what I am doing. For bulk or pistol ammo I use the Lee Safety Primer (the older version). It works great but did have issues with the handle breaking on tough brass. I bought a new XR version to get a replacement handle and even though the handle is different it works with the old primer. The XR handle in the old primer seems to work a lot better than in the XR or the old handle in the old primer. I tried using the XR and it is a pain in the but with its safety step in the process. I found myself clearing jams more often with the XR than the old Safety Prime. For times when i want a little more precision I use the Lee Ram Prime that mounts to the top of the press. It works great and uses the standard priming tray. The biggest thing I like about it is I can set the primer depth and have all cases come out with the primers the exact same height. You can't do this with a hand primer as the primer pocket itself determines the primer depth. And as I said I do this with precision loads where I want everything, including primer height, to be exactly the same. It is also the easiest way to seat primers. The Ram Prime went out of production a few years ago and it was a pain to find one but I am glad I did. I use it for all my precision needs and I think it helped shrink my groups. I also put a slight champfer on hard cases or cases that had crimped primers. It does make them a lot easier to load.
