Geissele Super Duty MOD1, SBR, 300 Blackout, DDC

The Super Duty MOD1 is the current evolution of the Super Duty platform, incorporating continuous design development to provide superior ergonomics and modularity while maintaining the legendary balance of performance and reliability. The Super Duty MOD1 300BLK upholds this legacy, featuring the latest in firearms technology. Front and center is the Geissele Cold Hammer Forged, Chrome Lined barrel, precision machined here in North Wales, PA from Chrome Moly Vanadium steel. Setting the Super Duty MOD1 300BLK apart is the patented Phased Array gas system, which utilizes multiple ports to precisely balance gassing and eliminate the need for an adjustable gas system. Combined with the Geissele braided buffer spring, this system provides a reliable and smooth shooting experience, whether shooting suppressed or unsuppressed with super or subsonic ammunition.
