Geissele Super Duty MOD1-A 5.56mm Ambidextrous 11.5" Bbl DDC Pistol 08-674S

Geissele Super Duty MOD1-A 5.56mm 11.5" Ambidextrous DDC Pistol 08-674S is the Desert Dirt Color counterpart to the Black 11.5" build — same mechanical spec throughout, just finished for a lower-visibility profile.

The 11.5" barrel is cold hammer forged, chrome-lined, and holds a 1:7 twist on Geissele's tapered profile, running through a carbine-length gas system with a .067" gas port tuned specifically to this barrel length. This Geissele Super Duty 11.5 configuration pairs that with a Super Compact Gas Block set for reliable cycling under sustained use, not just a handful of magazines at the range.

Fully ambidextrous controls carry over from the platform — a left-side magazine release below the Maritime Bolt Catch and a dust-cover-actuated bolt catch and release on the right, so the manual of arms doesn't change based on which hand is running the gun. Inside, a Nanoweapon-coated Reliability Enhanced Bolt Carrier Group runs with a forged Stressproof Bolt, and the SSA-E X® trigger with Lightning Bow® gives a clean two-stage break that holds up over high round counts. A 10.5" MK16 rail with Geissele's Center Tab mating keeps everything locked in place up front.
