The Geissele Super Duty MOD1 5.56 NATO AR-15 rifle is a premium AR-15 designed for exceptional accuracy, comfort, and reliability out of the box. Chambered in the popular 5.56 NATO round, this 16" rifle boasts a Geissele Super Duty lower for a solid foundation. The upper receiver is a Super Duty M4, and the heart of the rifle is the Geissele Reliability Enhanced Bolt Carrier Group with its chrome lined gas key and Nanoweapon coating for maximized wear resistance.

One of the highlights of this rifle is the Geissele SSA-E X trigger with Lightning Bow. This two-stage trigger is designed with a wide body and trigger bow that takes elements from the classic M4 trigger and flat-body trigger for the perfect balance. A 15" MK16 Super Modular Rail offers ample space for mounting accessories, while the mil-spec buffer tube with an H2 buffer ensures smooth operation.

Note: This rifle does not ship with a magazine.
