Geissele Super Duty MOD1 | 5.56 NATO | 16″ | 08-395B

The Geissele Super Duty MOD1 is a purpose-built modern sporting rifle combining a 16″ cold hammer forged, chrome-lined barrel and Geissele’s two-stage SSA-E X trigger for consistent, repeatable performance. This MOD1 configuration includes a HUXWRX Flash Hider-QD muzzle device, MK16 Super Modular Rail with press-fit stainless steel QD inserts, and a B5 Enhanced SOPMOD stock to deliver durable ergonomics for extended use. A compact gas system and Geissele Super Compact Gas Block are fitted to support reliable function under sustained operation. Recommended optic: Vortex Viper PST Gen II 1-6×24 pairs well for close-to-mid range work while staying well under typical upper-tier optic budgets.

Applications: precision-oriented target work and scoped field use such as marksmanship practice or competition stages where a rugged, repeatable AR platform is required.
