[QUOTE="mtwarych, post: 1194670, member: 70595"] I believe you should take the length of the gas system into consideration before you mount a 26 inch barrel on a gasser. The last thing you need is the bolt starting to unlock before the barrel is clear of slug and high pressure gas. I have a DPMS GII hunter that was over gassed and that rifle just destroyed brass before I put an adjustable gas block on it.(20 inch barrel) Even though it was a middle load 308, before the gas block, The rifle was uncomfortable to shoot and bucked around like a carp out of water. I am not sure where one would find the burn rate information compared to gas system length, but it has got to be out there somewhere. I am also not sure if one can get a custom length gas system for a longer barrel. Good luck. I would like to know what you come up with. [/QUOTE]
