AR10 guidance

[reed1285]

So I was gonna build another ar15 as my next project, but I have decided to spend the extra $ to build an ar10. It will be my first one, but im assuming they operate pretty much exactly like a 5.56 ar? are the lowers put together the same? Ive noticed how much more expensive it is to build one of these compared to a standard ar, so it will be a slow build. another thing Ive noticed is how DPMS has a strong foothold in the ar10 business. I type in a google search for ar10 lower receivers and its pretty much all dpms stuff. 1- why is that, 2- do any of you guys know where to find good ar10 stuff where there is more options than just dpms. Joebobs has nothing for them that i saw and Midwayusa just carries DPMS stuff. Thanks for any help and possibly getting me on the right foot

I have taken a DPMS down as far as pulling the barrel, gas block, etc. They're real similar, just quite a bit beefier. As I understand it, parts compatability between brands isn't near as good as the AR-15 Platform. I didn't see anything wrong with the DPMS rifle (for what little I know about them). The standard AR-15 tool fit the barrel nut on that one.

I have a DPMS LR-308AP4. I think you see DPMS more than the others because they are one of the few that still make a .308, some of the others gave up, with the exception of a couple (Armalite, Rock River, ?)

A .308 AR is sweet. But everything cost more because of the reduced manufacturing quantities. If they ever become mainstream the prices will be the same as for an AR-15.

I wanted to put a quad rail on mine, but shoot I could sell it and buy one with a quad already on it for less than they want for a quad for it, and then I would also have to buy the tools, which of course cost more because they are for a .308. It was like $150 more when I bought mine with quad. I thought I would just add it later after I decided what I wanted….. I was wrong.

I don’t think you could build one any cheaper than you could buy it set-up the way you want it from DPMS. But it might be a good project.

Yep. I was swapping a handguard for a fellow TGO'er. He had to buy the upper reciever block and a special tool for the free float guard. Still needed my armorer's tool for the barrel nut. Then, there was the weeked trip to Outpost for a gas block. Had to Dremel the pins out of the factory DPMS block.

Like DaveTN said... you may be better off buying one,
