AR10 barrel and Buffer recommendations

[Sigmanx]

Hey guys, I’m looking at either the Ranier Arms 16” rifle length gas 1:8 barrel or the SOLGW 16” midlength gas barrel. I’ve been looking at different Buffer systems, but no luck yet on which would run the smoothest. I’ll have aNOX and Sandman K on it too. Aero M5 Lower btw!

Thx!

Just based on gas system length this is no contest. Especially with a suppressor. Rifle gas for the win.

It is the barrel I’ve been heavily leaning towards myself!

If you were to ever run without the can using surplus or steel case ammo, mid length gas would probably be more reliable. Action/recoil for carbine adjustable stock, I'd go with an intermediate (A5) length receiver extension, H2 or H3 buffer and a 308 rifle length spring like the ArmaLite #EA1095.

I did hear back from SOLGW and they recommended an A5 tube with a green spring and H2 Buffer for the intermediate gas system.

H2 without the can might be OK, but MLGS w/can, I would be prepared for something heavier. KAK, and others, make a configurable AR-15 carbine buffer kit (correct for the AR-10/AR308 using an intermediate RE) that you can swap weights out to dial in up to 5.6oz.. Might help if you don't already have a variety of buffers to try. Some cans might need heavier than that, but I think the Sandman K is fairly low back pressure.

Intermediate or mid? Those are two very different things.

Midlength gas with the A5 Tube. Sorry about that!

Rlgs for 16". I'd consider going shorter with a pin / weld too.

That sandman k will be loud but the low back pressure will make it worth it. High back pressure cans aren't worth it on large frames.

Ya, I just don’t really have any interest in going shorter than that. I have a 8” 300blk and 11.5” 5.56 for shorter applications as well as a 16” 5.56!

I have a Criterion 16” rifle gas barrel that shoots good. It cycles with xm80, every factory ammo I’ve tried, and hand loads.

ETA: Armalite Carbine length RE with an H3 works.

Good to know. I hadn’t looked at them yet. Honestly didn’t even think about it. , but this rifle is mainly going to be eating M80 and M118 special ball if I can find it.

Did you ever finish this? If so, what did you use and hows it running?
