Barrel and Muzzle
The 7.5-inch "Akali" barrel is machined from 4150 chrome moly vanadium steel in an HBAR profile and finished in Parkerized (Phosphate), a matte, corrosion-resistant treatment that gives it a clean, uniform look. Its 1:10 twist rate is suited to a wide range of 9mm bullet weights. The muzzle is threaded 1/2x36, the common thread pitch for 9mm devices, and carries the included 9mm A2 birdcage flash hider.
Upper Receiver and Handguard
The upper receiver is a "Vertex" Enhanced Pistol Caliber billet unit machined from 6061-T6 aluminum and finished in Type III hard coat anodizing, a hard, wear-resistant surface that resists scratches and corrosion. It is built specifically for pistol-caliber applications. It is paired with a 7-inch aluminum handguard finished in black anodizing, which keeps the front end clean and uniform in appearance.
Bolt Carrier Group
The included 9mm bolt carrier group is machined from 416 stainless steel with a Nitride finish, which adds hardness and corrosion resistance and helps the carrier stand up to repeated cycling. It uses an external extractor and accepts both Glock and Colt pattern magazines.
Compatibility
This upper is built for AR-9 platforms chambered in 9mm (9x19). Charging handle inclusion, handguard attachment system and free-float or drop-in style, ejection port door and forward assist configuration, and the lower receiver magazine well pattern needed to match the Glock or Colt magazine style were not supplied with this listing and should be confirmed before purchase.
