Occam Defense Solutions
Our billet adjustable gas block is specifically designed to be compatible with our MERC handguard, but will also work just fine on classic AKMs and AK-74s. Rather than using the usual set screw, this design utilizes a gas cup with multiple aperture sizes around the rim. This cup, combined with a detent, allows the user to select between discrete sizes. The design has no screws; nothing to come loose under high temperature conditions! The gas cup design borrows heavily from historically rugged designs from HK, SIG, AK-12, and FN. As all gas blocks accumulate carbon, we've designed in a removal feature so that the cup can be removed from the front by rotating to the section of cutout flange and pulling towards the muzzle end of the barrel.
