<br />Reaver, does the bolt have gas rings on it like an AR15? If so make sure the gaps are spaced out to prevent blow by which will cause short stroking. The rings could also be worn to the point of not providing a good seal and need replacing. Check out Bushmaster's site for spare parts if you haven't already.

I can't say for sure Harley. My experience with M-16 style bolts is pretty limited. As a field medic, I'd shoot the guns and let the Marines clean 'em.
I'll take a look again when I get the chance.
