The new BCM MK2 Upper is the latest offering in firearms technology from Bravo Company Manufacturing. This new, optics and suppressor minded upper receiver seeks help shore up some of the inherent weaknesses of the standard AR platform.
In comparison to the older style of service rifles that featured integrated carry handles, the newer flat-top ARs had to be quickly adapted to accommodate optics as a standard feature. This resulted in the top of the upper receiver being weakened, specifically around the ejection port. BCM’s MK2 upper compensates for this fact by shifting material from non-critical to critical areas which reduces barrel deflection and enhances bore tolerances improving barrel alignment, consistency, and accuracy.
This enhanced rigidity aids accuracy by limiting barrel deflection from external loads such as a bipod or vertical grip. It also prevents unwanted deflection of moving components, reducing the chance for premature damage and wear of the bolt and barrel lugs which results from misalignment.
In addition to weapon optics, suppressors have also become standard in modern combat operations. The added gas expansion areas and new channels added around the charging handle opening vent gasses away from the end user’s face, reducing distractions when employing the weapon system with a can.
Fine-tuning the positioning of the forward assist creates additional clearance for right hand sided charging handle manipulation and clearance for endplate mounted slings.
The MK2 Upper Receiver also retains all USGI components in the assembly and works with all USGI bolt carriers, charging handles and barrel assemblies.
Forged from 7075T6, the BCM MK2 Upper Receivers retain a form following grain structure which maximizes achievable strength.
All of these improvements come without affecting the manual of arms employed in manipulating a Mil-Spec upper receiver.
All BCM components and accessories unite state of the art manufacturing with lightweight and durable materials to ensure components that last a lifetime, performing far beyond performance requirements established nearly six decades ago.
