Davidson Defense 9mm Upper Receiver

The Davidson Defense 9mm Billet Upper Receiver is made for 9mm AR builds. It is made from 6061 aluminum. The receiver is the foundation of the upper side of this kit. It pairs with the Air Lite Series Honeycomb handguard and its monolithic top rail.

6 Inch Nitride 9mm Barrel

The barrel is a 6 inch 9mm barrel made from 4150 CrMoV with a nitride finish. It uses a medium profile and a 1 in 10 twist rate. The muzzle uses a half inch x 28 thread pitch, the common thread for 9mm AR barrels. The short barrel keeps the AR-9 compact.

Air Lite Series Honeycomb Handguard and Omega Mfg Flash Hider

The Air Lite Series Honeycomb handguard measures 4 inches with a free float M-LOK design and a monolithic top rail in black anodized finish. The honeycomb cutout pattern gives the short front end a distinct look. An Omega Mfg A2 birdcage flash hider threaded half inch x 28 is included and is compatible with 9mm. A half inch black crush washer rounds out the muzzle hardware.

MVR Reflex Sight

The kit includes an MVR reflex sight. It offers red and green illumination so the shooter can pick the color that shows best. The optic is compatible with Picatinny rails, matching the monolithic top rail on the handguard and receiver. Having the optic included means the upper and its sighting option come together in one purchase.
