Description

The Pro2A Tactical 10.5-inch .450 Bushmaster Non-Reciprocating (NR) Side Charging Complete Upper Kit contains all the necessary components to transform a standard stripped lower receiver into an advanced, ergonomically superior big-bore platform. Proudly built and inspected in Georgia, this package introduces a rigid billet receiver that replaces the traditional rear charging handle with a static side-charging mechanism.
