Geissele Super Duty MOD1 - 5.56 NATO SBR 10.3" Barrel - Black

Taking Geissele Automatics’ flagship rifle platform to the next level of tactical capability, the Geissele Super Duty® MOD1 10.3" 5.56mm NATO Short-Barreled Rifle (SBR) in Black delivers match-grade precision, battle-ready durability, and smooth recoil management in a compact close-quarters footprint. At the core of the SD MOD1 is a 10.3-inch cold hammer-forged (CHF), chrome-lined barrel with a manganese phosphate coating and a 1:7" twist rate, rigorously subjected to High-Pressure Testing (HPT) and Magnetic Particle Inspection (MPI). Equipped with a carbine-length gas system, a tuned .070" gas port, and a bomb-proof pinned Super Compact Gas Block, the Super Duty MOD1 ensures soft, reliable cycling under extreme duty conditions.

Every critical component in the MOD1 SBR has been refined for unyielding performance. The rifle is equipped with the Nanoweapon®-coated Reliability Enhanced Bolt Carrier Group (BCG), featuring extended upper guide rails, an H13 tool steel cam pin, a chrome-lined gas key, and the ultra-durable Geissele Stressproof Bolt®. Upgraded with the 9.3" MK16 Super Modular Rail with press-fit stainless steel QD sockets and Geissele Center Tab receiver alignment, the upper comes fitted with a Nanoweapon®-coated HUXWRX Flash Hider-QD 556 for fast suppressor integration. Complete with the match-grade SSA-E X® two-stage trigger featuring a Lightning Bow® blade, an Airborne Charging Handle, a Super 42® spring with H3 buffer, an A17 pistol grip, and a B5 Systems Enhanced SOPMOD stock, the Super Duty MOD1 SBR represents the cutting edge of modern 5.56 carbine engineering.
