The heart of this pistol is its 12.5-inch 6mm ARC barrel, clearly caliber-marked, running a direct-impingement system with a low-profile set-screw gas block. The barrel is free-floated and threaded, with the PigPen open-prong muzzle device installed.
Noveske's NSR-10.75 aluminum handguard is a slim, free-float design with M-LOK slots and a continuous top rail that mates to the flat-top upper receiver. This setup provides a rigid, lightweight front end and uninterrupted mounting space along the 12 o'clock rail.
The rear features an SB Tactical SBA3 brace mounted on an adjustable carbine receiver extension with a Velcro strap. Ergonomics are rounded out by a B5 Systems pistol grip and a flat-faced trigger for a straight, consistent pull.
Controls follow the standard AR-15 layout, including a right-side magazine release and a manual safety selector. Capacity is 24+1, and the included E-Lander steel magazine is marked "6.5 Grendel," a common pattern used with 6mm ARC. No sights are included.
