The Geissele Super Duty MOD1 5.56 NATO rifle (Geissele part no. 08-395B) is a duty-grade AR built around a 16-inch cold hammer forged barrel and finished in black. Geissele ships it with the parts most owners swap out first already upgraded: an SSA-E X trigger with Lightning Bow, a 15-inch MK16 Super Modular Rail, a B5 Systems Enhanced SOPMOD stock and an A17 grip. A suppressor-ready HUXWRX Flash Hider-QD sits on the muzzle, so the rifle is ready for a can when you are. It suits patrol and home-defense use, training classes and hard range work where reliability matters more than anything else.
