Geissele Super Duty MOD1 SBR 5.56 NATO 12.5" Barrel DDC

Geissele Super Duty MOD1 5.56mm 12.5" DDC SBR 08-541S carries the same core Super Duty engineering as the ambidextrous MOD1-A builds, just on a standard Mil-Spec lower rather than the billet ambi receiver - a straightforward, proven configuration for shooters who don't need mirrored controls. The 12.5" barrel is cold hammer forged, chrome-lined, and cut to a 1:7 twist on Geissele's tapered profile, running a carbine-length gas system through a Super Compact Gas Block with a .065" gas port sized specifically for this length. This Geissele Super Duty 12.5 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. The Geissele MOD 1 Super Duty platform's SSA-E X® trigger with Lightning Bow®-gives a clean two-stage break, splitting the difference between a classic M4 trigger and a flat-bow design. An 11.5" SMR 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 for a solid cheek weld and sling attachment options.
