Thread: Waitaki Engineering Suppressor

The increased pressure was resulting in the bolts breaking at the cam pin hole prematurely. Bushmaster don't HPT/MPI inspect their bolts individually (last I heard) meaning the risk of a sub standard or flawed one getting into circulation is increased. Running a can on an AR can significantly increase the back pressure and chamber pressure. Running one on a carbine length gas system is even worse, as it is already over gassed to begin with - the chamber pressure is high as the bolt unlocks, meaning the lugs get torn out of the barrel extension, putting them under a lot of stress. Some manufactures exasperate this even more by drilling the gas ports too large, so the rifles will cycle with crappy under powered ammo like Wolf. I guess an adjustable gas block would be a sensible fix.

Thank you, wise advise, I was looking at a full piston kit but adjustable gas blocked run at about $99 US, wasnt sure if they would completely fix the problem but hey may as well grab one in the near future.

Actually there are some nice $56US ones.
