The Bravo Company MK2 Upper Receiver Assembly is forged upper that has some modern enhancements over the current M4 Mil-Spec receivers. The MK2 has shifted mass from non-critical areas to areas that could use more reinforcement for enhanced rigidity. The changes aid accuracy by limiting barrel deflection from external loads such as a bipod or vertical grip and prevents unwanted deflection of moving components, reducing the chance for premature damage and wear of the bolt and barrel lugs.
Now that suppressors are more common the MK2 has added gas expansion areas and new channels around the charging handle opening to vent gas away from the shooters face. The forward assist has been re-positioned to create additional clearance for right hand sided charging handle manipulation and gives greater clearance for end plate mounted slings. Even with all these changes the MK2 Upper Receiver retains compatibility with all USGI components and works with all USGI bolt carriers, charging handles and barrel assemblies.
Forged from 7075T6 Aluminum the MK2 Upper is fully assembled with forward assist, and ejection port cover installed. The Mil-Std 1913 Rail on the top has laser etched T-markings for addressing the remounting of optics. Made in the U.S.A.
