I lost the link wherein I asked this question, so here it goes again. When is it appropriate to use the "H" buffer? I have a 16" Dissy (with carbine length gas system) and it uses the standard buffer in a VLTOR A1 length stock and everything works well. Is the "H" buffer only needed when one is using a 14.5" barrel in conjunction with a collapsible stock because of the sharper recoil impulse? One last thing, isn't the Dissy's gas block located in the same place as the M4 gas block? Thanks for any feedback. EDITED TO ADD: Will the extra 1.5" barrel length (of the Dissy) lessen the recoil impulse when compared to a 14.5" M4 barrel? |

well, here is my take. I use the "H" buffer in my 14.5 barrel and I don't have any issues. However, I have always had the "H" buffer so I can't offer a before/after review. It does slow down the rate a little allowing the pressure to decrease before the bolt unlocks. I think it is worth it. my rifle has gone through some heavy blasting at my friends farm in PA and I have not run into problems. pick one up and try it out. it can't hurt. |

On the other hand, my XM177E2'd, 11.5 inch barrelled,class 3d,SP1 carbine w/the factory buffer has always worked just fine also; semi and full auto. I keep thinking about getting an H buffer to slow the cyclic rate a bit, but then I spot something else I want, so the money goes somewhere else

Colt supplies the 'H' buffer as standard equipment in both the MT6400C and the LE6920, both having 16" barrels. I don't think that the 'H' buffer is absolutely necessary on a SA w/ 16" barrel but it sure doesn't hurt either. My MT6400C with standard 'H' buffer will handle any ammo (that's worth a damn) as fast as I wish to fire it. On the other hand my R6001 (SP1 Carbine) will do the same with its standard original carbine buffer. The 'H' buffer really helped when I installed one in an 11.5" SBR in place of the standard carbine buffer. HTH |
