Geissele Super Duty MOD1-A 5.56mm 13.9" Bbl Ambidextrous P&W DDC Super Duty Rifle 08-672S

Geissele Super Duty MOD1-A 5.56mm 13.9" Ambidextrous P&W DDC Rifle 08-672S takes the same barrel and gas engineering as Geissele's ambidextrous SBR line and pins the muzzle device out to a legal 16" overall length, giving shooters the shorter handling characteristics of a 13.9" barrel without the NFA paperwork.

The barrel is cold hammer forged, chrome-lined, and cut to a 1:7 twist on Geissele's tapered profile, pinned and welded with a HUXWRX Flash Hider-QD 556. This Geissele Super Duty MOD1-A 5.56mm 13.9 build runs a mid-length gas system through a Super Compact Gas Block with a .079" gas port, feeding a Nanoweapon®-coated Reliability Enhanced Bolt Carrier Group. Inside, a forged Stressproof Bolt machined from Carpenter 158+ barstock holds up to sustained round counts that would start showing wear on a standard bolt.

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. The Geissele Super Duty MOD 1's SSA-E X® trigger with Lightning Bow® splits the difference between a classic M4 trigger and a flat-bow design. A 12.9" 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.
