Geissele Super Duty MOD1 5.56 NATO SBR – 11.5" Barrel, DDC, B5 SOPMOD Stock

Geissele Super Duty MOD1 5.56 NATO 11.5" DDC Short-Barreled Rifle

The Geissele Super Duty MOD1, manufacturer part number 08-522S, is a semi-automatic short-barreled rifle chambered in 5.56 x 45mm NATO. This configuration features an 11.5-inch cold hammer-forged, chrome-lined barrel, carbine-length gas system, 10.5-inch MK16 Super Modular Rail, B5 Systems Enhanced SOPMOD stock, SSA-E X Lightning Bow trigger, and Desert Dirt Color (DDC) finish.

The supplied product information identifies this firearm as a short-barreled rifle (SBR). It uses a standard Mil-Spec lower configuration rather than the billet fully ambidextrous MOD1-A receiver configuration.

11.5-Inch Cold Hammer-Forged Barrel

The Super Duty MOD1 uses an 11.5-inch cold hammer-forged barrel with a chrome-lined bore and a 1:7 twist rate.

The barrel features Geissele's tapered profile and a 1/2x28 muzzle thread pattern.

Carbine-Length Gas System

The supplied product information identifies a carbine-length gas system paired with Geissele's Super Compact Gas Block.

The 11.5-inch configuration is listed with a .067-inch gas port sized for this barrel length.

Reliability Enhanced Bolt Carrier Group

The rifle is equipped with Geissele's Reliability Enhanced Bolt Carrier Group featuring a Nanoweapon coating.

The supplied description also identifies a forged Geissele Stressproof Bolt manufactured from Carpenter 158+ barstock.

SSA-E X Lightning Bow Trigger

The Super Duty MOD1 features Geissele's SSA-E X two-stage trigger with Lightning Bow. The supplied product description characterizes it as providing a smooth first-stage take-up followed by a crisp second-stage break.

10.5-Inch MK16 Super Modular Rail

The rifle uses a 10.5-inch Geissele MK16 Super Modular Rail with Geissele's Center Tab interface.

A full-length Picatinny rail provides a mounting surface for compatible optics and accessories.

B5 Systems Enhanced SOPMOD Stock

This SBR configuration includes a B5 Systems Enhanced SOPMOD stock mounted on a Mil-Spec buffer tube. The supplied specifications also identify a QD endplate.

The adjustable stock contributes to a listed overall length of approximately 29 inches when collapsed and 32.25 inches when extended.

Airborne Charging Handle

A Geissele Airborne Charging Handle is included in the Super Duty MOD1 configuration.

Controls and Safety

The supplied specifications identify a Geissele Super Configurable Safety Selector and list the firearm's handedness as ambidextrous.

Because the supplied description identifies this version as using a standard Mil-Spec lower rather than the billet MOD1-A lower, this listing does not characterize the rifle as having fully mirrored bolt and magazine controls.
