| Which buffer do I need ot run for a 11.5" BCM barrel chambered in 5.56, with a carbine gas system and an SRT Hurricane suppressor? Thanks in advance! |
| I think most people would almost reflexively say a heavy buffer. Something like Spikes T2. But I can attest first hand that you won't know for sure until you shoot it. I have a 10.5" barrel, carbine length with a PSA H buffer and it seems very under gassed. Best thing I can figure out to do is shoot hotter ammo and get a lighter buffer and/or weaker recoil spring. But there's no guarantees until you get out there and shoot it. |
| H buffer for 16-11.5, h2 for 10.5, sub 10.3 h3. That's a general rule. Colt 6933's 11.5 inch barrel come with an h buffer. Id shoot bcm an email and ask them what they put on there complete 11.5 guns. It should be no problem using the same buffer surpressed and unsurpressed. |
