The forged 7075-T6 aluminum lower receiver is marked “Surplus Ammo & Arms LLC – Lakewood, WA” and carries SAFE/FIRE pictograms. Paired with it is a Del-Ton 20-inch chrome-moly barrel featuring a rifle-length gas system, 1:9" right-hand twist, and a standard A2 bird-cage flash suppressor threaded 1/2-28.
For handling, the rifle uses a six-position collapsible stock, letting the shooter adjust length of pull while still benefitting from the longer sight radius of the rifle-length upper. The A2-pattern pistol grip and two-piece polymer handguard complete a familiar, no-nonsense control setup.
An upgraded trigger assembly replaces the standard mil-spec unit, providing a cleaner, more responsive break that aids practical accuracy. The manual safety selector remains in the usual position for intuitive operation.
Iron sights include an F-marked, pinned A-frame front post and a detachable A2 aperture rear sight, giving dependable aiming references right out of the box. The flat-top upper receiver’s integral rail allows additional accessories if desired in the future.
