Aegis 7.5-Inch 1:10 9mm AR-9 Free-Float M-LOK Handguard Pistol Complete Upper
The Aegis Complete Upper is built around a 7.5-inch 9mm (9x19) barrel machined from 4150 chrome moly vanadium steel in an HBAR heavy profile with a Phosphate finish. It is paired with a 7075-T6 aluminum upper receiver and a free-float M-LOK handguard, and it ships with a 9mm bolt carrier group and a mil-spec M4 charging handle, so the builder receives the core working components of an AR-9 upper in one package. The heavy profile adds a sturdy feel up front, and the 1:10 twist suits a wide range of 9mm bullet weights.

Barrel and Muzzle
The 7.5-inch barrel is machined from 4150 chrome moly vanadium steel in an HBAR profile and finished in 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 machined from 7075-T6 aluminum and finished in anodizing, giving it a hard, wear-resistant surface that holds up to regular handling. It is paired with a free-float M-LOK handguard, also finished in anodizing. As a free-float design, it leaves the barrel free of handguard contact, and the M-LOK slots give the builder room to mount lights, grips, handstops, and other accessories wherever the setup calls for them.
Bolt Carrier Group and Charging Handle
The included 9mm bolt carrier group has a carrier machined from 8620 alloy steel with a Nitride finish, which adds hardness and corrosion resistance and helps the carrier stand up to repeated cycling. It is paired with a mil-spec AR-15/M4 charging handle, completing the upper so it is ready to be matched with a compatible lower receiver.
Compatibility
This upper is built for AR-9 platforms chambered in 9mm (9x19). Handguard length and color, ejection port door and forward assist configuration, extractor style, and the lower receiver magazine well pattern needed to match the bolt carrier group's magazine compatibility were not supplied with this listing and should be confirmed before purchase.
