Description

This complete .300 AAC blackout build kit features a 16″ barrel and comes with a 12″ handguard and standard A2 birdcage flash hider.  The handguard features a picatinny top rail and plenty of keymod attachment space, which gives it a couple different ways to mount attachments such as foregrips or tac lights.

Mil-Spec Quality and Accuracy

The upper assembly features a barrel chambered in the .300BLK caliber and is manufactured from mil-spec 4150 chrome moly steel, offering superior barrel life and accuracy.  Each barrel is built with the intent of providing 1 MOA accuracy at 100 yards (dependent upon user ability). It also features a carbine gas system to reliably cycle any .300BLK load, light or heavy. Hand-built in the USA, the upper assembly features a standard flat top M4 upper receiver with Type III Hard Coat Anodized finish (mil-spec), and M4 feed ramps.

Need a California-Compliant Build Kit? Follow These 4 Steps!

1. Choose “CA-Compliant Lower Parts Kit” in the Lower Parts Kit dropdown.

2. Choose the “No Lower Receiver” option for the 80% Lower Receiver dropdown.

3. Select/Click “Add to Build”.

4. Head here to purchase a California-compliant 80% lower receiver

Please note: This AR-15 Build Kit requires that the builder completes the 80% lower receiver themselves, but that’s the fun part (and the only way to build your own AR-15 without the need of an FFL transfer or serialization).
