AIA-AR-5.56×45-Mk1-[BL]

The AIA-AR-5.56×45-Mk1-[BL] is a modular 5.56×45 mm infantry rifle for professional defence, law-enforcement and specialist applications. Three barrel lengths support compact, general-purpose and extended configurations.

The system uses short-stroke gas-piston operation, a three-position gas regulator and a free-floating, hammer-forged, chrome-lined barrel. The upper receiver provides a continuous accessory rail, with a modular handguard and adjustable stock.
