The heart of this rifle is its 16-inch 4150 CMV barrel, nitride-treated for corrosion resistance and longevity. A 1:7 right-hand twist stabilizes the full spectrum of 5.56 NATO and .223 Rem loads, from light-varmint bullets to heavier defensive rounds.
Forged 7075-T6 aluminum upper and lower receivers are hard-coat anodized in matte black. The lower is marked “MULTI,” allowing straightforward caliber conversions with compatible uppers.
The free-float 13.5-inch aluminum M-LOK handguard leaves the barrel untouched for enhanced accuracy and offers uninterrupted top rail space for optics. Side and bottom M-LOK slots accept accessories without adding unnecessary weight.
A carbine-length gas system with a low-profile gas block balances reliability and recoil impulse. The direct-impingement action, manual safety selector, and M4-style six-position stock maintain familiar AR-15 ergonomics.
The rifle ships ready to run with a 30-round magazine and practical upgrades already installed—a Streamlight ProTac Rail Mount light for target identification and an angled foregrip for improved control.
