Geissele Super Duty MOD1-A 5.56mm 16" Bbl Ambidextrous DDC Super Duty Rifle 08-670S

Geissele Super Duty MOD1-A 5.56mm 16" Ambidextrous DDC Rifle 08-670S runs full-length rather than pinned and welded, giving up nothing to the shorter MOD1-A configurations in exchange for the added velocity and sight radius a 16" barrel provides.

The barrel is cold hammer forged, chrome-lined, and cut to a 1:7 twist on Geissele's tapered profile, running a Geissele-length gas system through a Super Compact Gas Block with a .075" gas port. This Geissele Super Duty MOD1-A 16 build channels that gas through a Nanoweapon®-coated Reliability Enhanced Bolt Carrier Group with a forged Stressproof Bolt, holding up to sustained round counts better than standard bolts.

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 reloads stay instinctive regardless of which hand is running the gun. This Geissele Super Duty 16 platform's SSA-E X® trigger with Lightning Bow® delivers a crisp, repeatable break. A 15" MK16 rail with Geissele's Center Tab mating keeps the front end rigid, and a B5 Systems Enhanced SOPMOD stock rides a mil-spec buffer tube with QD endplate.
