Geissele Super Duty MOD1-A 5.56mm Ambidextrous 14.5" Bbl Black SBR (NFA) 08-759B

Geissele Super Duty MOD1-A 5.56mm Ambidextrous 14.5" Black SBR 08-759B sits right at the sweet spot for a duty-oriented 5.56 NATO SBR - long enough to keep velocity where it needs to be, short enough to stay fast through doorways and vehicles.

The barrel is cold hammer forged, chrome-lined, and holds a 1:7 twist on Geissele's tapered profile, running on a mid-length gas system tuned around Geissele's Super Compact Gas Block, so cycling stays smooth and felt recoil stays low no matter what 5.56 load is running through it. This Geissele Super Duty MOD1 build carries the same barrel and gas engineering found across the whole line - nothing here is a scaled-down compromise.

Fully ambidextrous controls carry over directly from the platform: a left-side magazine release below the Maritime Bolt Catch speeds up reloads for left-handed shooters, while a dust-cover-actuated bolt catch and release button on the right keep the manual of arms instinctive regardless of hand dominance. This Geissele Super Duty MOD1-A platform's SSA-E X® trigger with Lightning Bow® delivers a crisp, repeatable break shot after shot, and the B5 Systems Enhanced SOPMOD stock rides a mil-spec buffer tube for a solid, adjustable cheek weld.
