The heart and soul of our AR-15 build is the BCM 16'' Mid-Length KMR Upper with the ALPHA 13 rail system! This system is AWESOME!
On the recommendation of my brother who is a USMC 0311 Infantry Marine who asserted that BCM was a company of former Tier 1 Special Forces Operators who are now manufacturing the "Best of the Best" in AR-15 equipment. As I considered my options I concluded that for the reasons that I wanted an AR-15 I wanted the best, most reliable upper that I could get so that if in the event I need to use it for the defense of life or liberty it will perform as designed with 100% reliability!
The simple fact that guys at BCM are manufacturing these parts to the needs and standards of the special forces community (being the best of the best themselves in their former military careers) , the fact that all parts and manufacturing are 100% "Made in the USA' and the fact that by supporting BCM we are supporting Our Veterans - the decision to choose BCM was an easy one!
