I have limited personal experience with .308 AR builds and I was wondering if anyone has had good luck playing with different buffer weights in lieu of an adjustable gas block. I have Tungsten weights floating around and it got me thinking.
I'm in the process of putting together an Aero M5 build and it's what got me thinking about it. For this one I'm using a Ballistic Advantage 16" Hanson barrel(mid length) and I was just going to order the Aero .308 Carbine Buffer kit. I'll be running a Sico Omega as well. The plan is an SLR adjustable gas block at the moment but I was just curious if an "H3" type buffer is even an option. |
| It's really better to have both an adjustable gas system and different buffer weights to play with as well. I mean you can of course use a standard gas block and just play with buffers to get it to function. But if you plan on using a suppressor for instance, it'll always be over gassed. If you never plan on using a suppressor, then I'm sure you'll be fine without an adjustable gas block. Of course I still think it's more desirable to be able to tune the gas system perfectly to your ammo. |

I suspect you'd be happier with the SLR adjustable gas block.... especially considering you're silencer comment.
My PA10 had such a large volume of gas ( gas port was in the proper range ) that even with a rifle length AR10 tube , Tubbs .308 spring and KAK 9.3oz AR10 rifle length buffer it was cycling pretty fast.... the SLR stopped all that nonsense. I bought the dimpling jig as well, and the medium length 2mm (?) adjustment tool. I couldn't be happier. |

Run the heaviest buffer you can. Keep that bolt locked as long as possible. I run a 9mm solid SS buffer turned down to DPMS carbine .308 length then milled out to hold a H3 weight set. Armalite AR10 OEM spring is recommended as well.
Lots of extractor issues on plated .308 extractor's. (NiBo, Chrome, Nickel) Most are just plated over tolerance making the grip edge rounded and killing the grab. Get 2 D Fender Oring's and a OEM DPMS extractor if you have any issues. |
