The GHM is a cost-effective, competition-oriented PCC featuring many of the same great qualities that made the APC9 so successful, while providing the user with additional levels of flexibility and modularity. Our Gen2s allow users to change barrel lengths, handguards and stocks with ease and adding an SD kit and other accessories is just as uncomplicated. The GHM9 accepts all APC9 PRO lower receiver groups, offering compatibility with GLOCK, SIG P320 and proprietary B&T magazines simply by switching the non-serialized lower receiver group. Standard equipment includes backup sights, top-side, fore-end side and under-barrel rails, B&Ts recoil-reducing hydraulic buffer system. Includes sling, cleaning kit, soft case and one 30rd magazine.
