BCM Prototype upper?

[LSGriff]

Cool, maybe it wont be too long. I'm wanting to build up a lower I have with a 16 mid for a recce type build. I wouldn't be opposed to buying a complete upper.

Go get em! in stock on website now

With no knowledge of when (or if) it would be offered as a stripped receiver, I ordered an MUR-1A a few days ago. It arrived today, so it's only natural for BCM's upper to be available today....also stripped.

Looking forward to using them to finally finish some complete uppers. Merry Christmas everyone!

BCM MK2 UPPER RECEIVER
Redesigned by lessons learned in combat since 9/11, the BCM MK2 Upper Receiver is built with up to 30% more rigidity than the current Mil-Spec M4 upper receiver without sacrificing interoperability for a mere additional 1/3 ounce of weight.


MEET THE NEW WAR
SAME AS THE OLD WAR
Upper receivers with baked in carry-handles and iron sights have been relegated to history. Optics are now synonymous with forward deployed combat carbines, featuring modular "optics ready" flat top upper receivers. Driven by a sense of urgency to improve lethality and save American lives in real-time, this innovation of the current M4 Upper Receiver has inadvertently introduced a degradation in the rigidity of the upper receiver, with the weakest point being the area around the ejection port.
Shifting mass from non-critical to critical areas; the BCM Mk2 Upper Receiver 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. 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.


LETHALITY IN THE DETAILS
In addition to weapon optics, suppressors have also become standard in modern combat operations. Added gas expansion areas and new channels added around the charging handle opening vent gases 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 end plate mounted slings.
All these improvements come without affecting the manual of arms employed in manipulating a Mil-Spec upper receiver.


BUILT TO EXCEED
Forged from 7075T6, the BCM MK2 Upper Receivers retain a form following grain structure which maximizes achievable strength, the MK2 Upper Receiver retains all USGI components in assembly and works with all USGI bolt carriers, charging handles and barrel assemblies.


MADE IN AMERICA
All BCM components and accessories unite state of the art manufacturing with lightweight and durable materials to ensure components that last a lifetime, perform far beyond performance requirements established nearly six decades ago.

There's a channel milled into the rear lug area, is that for gas/blowback........something else?

Just bought a stripped mk 2 upper. Im pretty excited for it

When did this place become twitter?

Allow me to retort. A couple of people on this thread were questioning whether or not the stripped upper receiver would be available. Therefore, as I simply stated I was able to purchase one and was excited about it.

The price on there is pretty good. I wonder if it'll be as good for heavier barrels as the MUR.
