The MOD1 300BLK continues this tradition, showcasing cutting-edge technology available exclusively from Geissele Automatics.
At its core is the Geissele Cold Hammer Forged, Chrome-Lined barrel, crafted in North Wales, PA from Chrome Moly Vanadium steel for unmatched durability and precision. Distinguishing the MOD1 300BLK is the patented Phased Array® gas system, featuring the Geissele Tri-Port™ design to optimize gas flow and eliminate the need for adjustable systems.
