When I was at S.A.W. two weeks ago they said they run the H buffer on 16 inch carbeans. 14.5" and down and they start getting into the H2 and H3 realm.

I run an H, that came with the gun, on this. If it was giving me trouble, I'd try an H2 and see what happens. I happen to be of the opinion that you should find the heaviest buffer that will work (both suppressed and unsuppressed which ever is more finicky) and stick with that.

Thanks Rob_s. You zeroed in on exactly what I was getting at. I tried an H3 in my 11.5 inch Sabre, and it seemed to run it fine with mild ammo... hand loads and AE223
I'm wondering if I should go with something heavier than the H buffer on a full time basis.
I run an H3 because that is what Specialized Armament put in when they did the reliability upgrade on my 6933's. I can tell a difference between the H3 & H buffer when running the gun suppressed.
I was told that by Ken at SAW that the H3 buffer is the best for reliability in a Commando and H2 is best in an M4.
that's roughly what Tina told me. But she also recommended that I run UMC ammo..... draw your own conclusions. :eek:
On my 10.5", 11.5" and 12.5" guns I use H2 buffers. I also have pretty large gas ports. If they had smaller gas ports I could use lighter buffers. All three were made to run unsuppressed and suppressed.
My 6933's with H buffer were beating up firing pin retaining pins pretty bad until SAW put the H3 buffer in. I was replacing them at about 250 round intervals, now I have had close to 2.5K through one of them and the pin looks fine.
What's a good source for H2s and H3s? I might give one, or both, a shot in my 6933s.
