Description

This complete build kit chambered in .300BLK features a 16" barrel and comes with a standard A2 birdcage flash hider and a 12" handguard.  The handguard features a picatinny top rail and keymod attachment system, which gives it a couple different ways to mount attachments such as foregrips or tac lights.

Mil-Spec Quality and Accuracy

The .300 AAC blackout upper assembly features a barrel manufactured from mil-spec 4150 chrome moly steel, which provides superior barrel life and accuracy.  Each barrel is built with the intent of providing 1 MOA accuracy at 100 yards (if you can manage, of course). 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.
