The Noveske N4 OG DDF 12.5" 6mm ARC FDE SBR is an elite, 4th-generation direct impingement short-barreled rifle purpose-built to maximize the performance of the long-range 6mm ARC cartridge from a compact footprint. Precision machined from a matched set of billet 7075-T6 aluminum Gen 4 receivers with a Flat Dark Earth Cerakote finish, this NFA-regulated platform hosts a heavy 12.5-inch 416R stainless steel barrel utilizing a proprietary Disruptive Deep Flute (DDF) profile that dramatically increases rigidity and accelerates barrel cooling by up to 40%. It comes outfitted with a free-floating 10.75-inch Gen 4 NSR M-LOK handguard, premium Magpul MBUS Pro steel folding backup sights, and a 5/8x24 threaded "Pig Pen" flash hider optimized for suppressor pairing. Exceptional handling dynamics are provided by a flat-bow two-stage Geissele Super Dynamic-Enhanced (SD-E) trigger system, a dual "Love Handle" charging handle, and fully ambidextrous lower controls with a Badger Ordnance C1 safety selector. Ergonomics are completed with a comfortable B5 Systems Type 22 pistol grip and a multi-position B5 Systems Bravo adjustable buttstock riding on a mil-spec receiver extension paired with a heavy H2 buffer.
