Description

This AR15 upper receiver assembly comes ready to attach to any Mil-Spec lower receiver. It is built around a 16 inch, 4150 chrome moly barrel and has a black nitride finish. The upper receiver is a forged M4 flat top upper, allowing you to easily attach rifle scopes and red dot sights to the picatinny rail. Additionally, this is a side side-charging upper which is a great way to add some pizzazz to your AR-style rifle, and they bring some practical benefits and functional improvements as well.

Outfitted with a 15″ M-LOK Rail that contains generously sized M-LOK cuts, this upper assembly allows for maximum air circulation around the barrel for faster cooling and keeps the handguard from getting hot to the touch. The rail also features a full-length picatinny top rail that sits flush with the upper receiver and has anti-rotation tabs to keep it locked in place.  This complete upper assembly comes with a standard A2 flash hider that effectively suppresses muzzle flash and protects the 1/2×28 barrel threads if you are planning on adding a muzzle break in the future.

➲ Pistol Length Gas Tube

An essential component to your AR15 is the gas tube, which keeps your build up and running. This gas pistol-length tube is constructed from corrosion resistant stainless steel ensuring a lifetime of service.

➲ .750 Low Profile Gas Block

The gas block is a critical link in the chain that is too often overlooked. This component ensures that your AR runs reliably. Made from high-quality steel with a smooth nitride finish, this .750 low-profile gas block is efficiently designed to stay put with the percussion of gunfire. With its low profile this gas block allows it to fit under the most ergonomically designed handguards and rails on the market.

➲ Barrel

The barrel is one of the few components that directly affect the accuracy and weight of your build.  This barrel has a nitride finish for increased strength and durability. This provides not only an impressive barrel life but ensures excellent accuracy. The barrel threads are carefully threaded to the .308 standard. Optimized for stability with a 1:8 twist rate, this 300 BLK barrel can handle heavier bullets used for subsonic loads with ease. 

➲ AR15 Muzzle

Not all muzzle devices are created the same. There aren't many muzzle brakes and compensators that demonstrate high-pressure gas dynamics. This AR-15 Muzzle Brake has a three chamber design that significantly reduces muzzle rise.
