The Noveske N4 OG Lo-Pro 12.5" 6mm ARC SBR is an elite, 4th-generation factory short-barreled rifle precision engineered to deliver maximum long-range ballistic efficiency from a highly maneuverable compact footprint. Built on matching 4th-Gen billet 7075-T6 aluminum receivers finished in an Armor Black Cerakote, this NFA-regulated platform hosts a premium 12.5-inch 416R stainless steel barrel with a hand-polished match chamber and a smooth, consistent mid-length gas system. It comes fully optimized for hard-use deployments with a 10.75-inch free-floating NSR M-LOK handguard, premium Magpul MBUS Pro steel folding backup sights, and a 5/8x24 threaded "Pig Pen" flash hider optimized for direct suppressor integration. Exceptional shooter control and physics are driven by a flat-bow two-stage Geissele Super Dynamic-Enhanced (SD-E) trigger system, an ambidextrous "Love Handle" charging handle, and fully ambidextrous lower controls with a Radian Talon short-throw safety selector. Handling control is rounded out with a comfortable B5 Systems Type 22 pistol grip and a multi-position B5 Systems Bravo adjustable buttstock riding on a 6-position mil-spec receiver extension.
