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

The Geissele Super Duty MOD1-A 5.56mm Ambidextrous 14.5 SBR 08-759S sits right at the sweet spot for a duty-oriented 5.56 NATO rifle - long enough to keep velocity where it needs to be, short enough to stay fast through doorways and vehicles. It carries the same mechanical DNA as Geissele's larger Super Duty builds, just trimmed to a more maneuverable length.

A cold hammer forged, chrome-lined 14.5" barrel with a 1:7 twist runs 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 is the same barrel and gas engineering found across the Geissele Super Duty MOD1 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. The 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.

This 14.5 Geissele Super Duty build ships with a 13.5" MK16 rail featuring Geissele's Center Tab mating system, keeping optics and accessories mounted square and locked in place.
