Geissele Automatics Geissele Super Duty MOD1-A 5.56mm Ambidextrous 12.5" Bbl Black SBR (NFA) 08-694B

Geissele Super Duty MOD1-A 5.56mm Ambidextrous 12.5" Black SBR 08-694B compresses the full Super Duty MOD1-A component spec into a shorter, more maneuverable package - same bolt, same trigger, same barrel process as the rifle variants, just cut down for close-range work. The 12.5" 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 .065" gas port tuned specifically to this barrel length. This Geissele Super Duty 12.5 build 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 this Ambidextrous AR15 stays fast to reload regardless of which hand is running it. 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. An 11.5" MK16 rail with Geissele's Center Tab mating keeps everything locked in place up front.
