Blitzkrieg Tactical Free Float Berzerker™ Complete Upper Receiver
In stock and ready to ship.
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.

QPQ: This is an extreme case hardening process which turns the steel black and hardens the surface of the steel and extends the life of the product. QPQ stands for Quench Polish Quench. This process is now commonly used in the industry.
