ADJUSTABLE GAS BLOCK

Shipping now!

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.
