This lower starts its life as a mil-spec 7075 forging. From there we take the forging and machine it into a mil-spec 80% lower. After the machining process is done, we send it out to get Type III hard coat anodized (mil-spec anodizing). The rear pocket is cut on this lower.

All machining processes have been completed and within spec except for the following:

1. Milling out the receiver interior (Fire Control Cavity).
2. Cutting of the Trigger Slot (Trigger Through Hole)
3. Drilling of the Trigger Pin Hole
4. Drilling of the Hammer Pin Hole

The Berzerker complete upper receiver is a dominating force to be reckoned with. With an 16" 4150v QPQ Barrel, shooters are able to benefit from the durability of mil-spec steel with the accuracy retention of the QPQ finish.

Furthermore, the Super Skinny, light weight 15" M-Lok rail keeps the upper nice and light for those who shoot matches or plan on taking their rifle into the field.

TEST FIRE: Most other companies do not test fire their products, and if they do it is usually a "lot" test. We test fire each and every upper. We shoot three shots and do so in rapid succession. Test firing allows us to be confident that the upper we are sending you is ready to go out of the box. We do our test fires dry and recommend that you lubricate your upper prior to shooting it.
