yeah.. it's pretty lame in this area..

This is where i was looking at buffers at https://pur-tungsten.com/products/sporting-goods/ar15-accesories/ As for the upper.. it's a Sabre Defense forged upper. Do you like the JP Captured Spring system? Yes i have thought about putting the tungsten weights in the buffer that i have now..

might try the orange spring.. thanks for the tip on the Sprinco Springs..

oh and i once had a AR10 built.. never could get the gas tamed on that one.. it would cycle the bolt carrier so fast that it was capturing the brass before it was getting out of the port

i can use the A1 buffer tube i have if i have to.. since i will only be shooting it prone. Which i may do.. You "assumed" correctly that it is a 20" barrel with a rifle length gas tube. Adjustable gas blocks are not allowed. As for the barrel, it is a Shelin 7.5 twist 4 groove barrel.. How fast and what powder load are you using with your 77's? Have you shot yours at 600 yards and further with yours.. ??? As for a tool, it's pretty common thought.. that if your brass is landing 1230 to 230.. you are over gassed.. 3 to 430 is perfect, 430 to 530.. the carrier is going too slow. i am not hip to all this new tech with buffers and springs.. been told about the use of the Gissele springs, but to be honest, he just wants way too much for those. I found the company that makes the buffers for everyone that sells them.. and they sell direct.. so it is a matter of now much weight i should go for to slow this carrier down. I have also considered a JP Silent Captured Spring system too

I don't post much.. This is for all you "experts" with the AR15.. Rifle is a AR15 Service Rifle.. I need to slow down the buffer.. when i put this together.. no one had anything in stock local or from what i could find online.. so when i installed the UBR 2 Buttstock on the rifle, it was a carbine length tube.. all i had was a rifle length spring.. through trial and error, i eventually got the carrier to lock back with the spring at 10" and the rifle buffer shortened to 3.1 inches and it weighs 3.0 ounces.. tested the system with Hornady Frontier 55 gr pills.. system was kicking the brass out at 330.. that's good. Now my new 600 yard load is lapua brass, Nosler CC 80's and 26.3 grs of 2000MR. With this load, the brass is getting sent out at 1230.. which means the system is getting over gassed. So I need to slow the carrier down some.. So the question is, use an H2 (4.6 oz) or should i go for the H3 (5.5 oz) tungsten buffer. The length on the new buffer would be 3.25 inches.. so i am going to presume that i should take another half inch off the spring.. What say you?

.223 all the way to a 1000 yards.. it's a lot of fun!
