The medium profile balances weight and rigidity for reliable performance in a compact format. With a 1:10 twist rate, this barrel ensures dependable function with 9mm (9x19) ammunition, stabilizing a wide range of bullet weights commonly used in pistol-caliber carbine applications. The barrel is fitted with a 9mm flash hider A2 birdcage for effective muzzle control and reduced flash signature.

The upper receiver constructed from durable 7075-T6 aluminum includes M4 feed ramps for enhanced feeding reliability with various 9mm ammunition types and bullet profiles. This enhancement ensures smooth feeding and consistent function, particularly important for 9mm AR-15 platforms. The 7" freefloat M-Lok handguard made from lightweight 6061-T6 aluminum ensures seamless attachment of accessories including lights, lasers, grips, and other attachments via the M-Lok interface.
