Re: buffer weights
The difference in buffer weights came into play with the advent of shortened barrels in carbine applications where gas is tapped closer to the breach with correspondingly greater pressures. The premise is to slow the opening of the action and therefore "time" the opening and closing so that the extractor is not pulling against a still expanded case and so the BCG inertia would be closer to its normal operating parameters. Typically the carbine buffers will be marked as H1, 2, and 3 and have increasing weights. The same can be done with rifle type assemblies using the carrier weights sold by Tubb under Superior Shooting Systems. This approach is typically more forgiving of high and low power loads than running a reduced weight BCG and tuning the recoil spring.It will however be higher in weight and will neither shoot as fast or be driven to target as easily.

Re: buffer weights
Well said Toolmakr. I like to run H2 on my SBR AR-15 with suppressor. Its help slow down the BCG and reduced recoil. I think the longer dwell time helps the accuracy too.

Re: buffer weights
Heavybuffers.com also have various weights.
I usually run their 10oz buffer in my .308 rifle length systems, and their carbine buffer for anything carbine length or middy.

Only change it if you are having a problem.

What he said with the caveat: if you are running a suppressor the heaviest buffer that will reliably operate unsuppressed is probably a good idea. Regardless of marketing bull shit all suppressors increase back pressure and bolt speed somewhat.

+1 I run 6 tungsten weights and a wolf XP spring in my 7.62 LMT w/ rifle length buffer, it keeps the 16" suppressed beast from slamming backward.

Re: buffer weights
Why not install a adjustable gas block? This will take care of any over gassed problems and really smooths out the recoil impulse. I will not own a DI AR without one.
Take care,Stan

Re: buffer weights
Has anyone figured out an adjustable gas block for the LMT mws w/ 16" barrel?

Edit: From lack of response(s) I take it the process was a phone call and going with Slash's recommendation. I am fine with that of course, the man knows buffers. I went with a JP adjustable gas block, worked great on a .308 carbine length system.
