Don’t let anyone tell you that all AR-15s are the same.
They may look similar on the outside, but the way they’re made and the materials they’re made from tell the true story. If you’re a casual shooter and plinker, this might not matter, but to those who wear the uniform and put their lives on the line every day, it’s critical.At first blush, the Bravo Company Manufacturing (BCM) M4 Mod 3 looks like any other AR-15/M4-type carbine. The 16-inch, M4-contour barrel features a cutout for the M203 grenade launcher and is topped with an A2-style fixed front sight tower. The stock is a standard M4-style, collapsible model, and the upper and lower receivers feature a matte black hardcoat anodized finish.
With that said, looking deeper at the BCM M4, you will find all the extras that separate Bravo Company’s ARs from other run-of-the-mill AR-15s. There are a lot of manufacturers’ AR-15s that work great for plinking, shooting for fun and hunting four-legged animals, but there are a limited number of companies who make AR-15s that you would carry when lives are at stake. The BCM M4 Mod 3 is one of them.
BCM is located in Hartland, Wisconsin, and was founded in 2003 by Paul Buffoni. The company started building complete rifles in 2008 with all BCM parts being 100-percent American made to U.S. government print specifications. What sets BCM apart is mil-spec quality. No shortcuts or substandard parts are used in BCM rifles. When the rifle is going to possibly be used to save a life, you don’t want a product made with manufacturing or assembly shortcuts. BCM products and rifles are solely designed and manufactured to go into harm’s way.
Let’s start with what everything gets attached to: the BCM receivers. AR-15 receivers are generally made from one of two types of aluminum. Most manufacturing companies use either 7075-T6 or 6061-T6 aluminum. The first four digits of the number “7075” give you the aluminum type of alloy, while the “-T6” tells you the material was heat treated and artificially aged. 7075-T6 aluminum is one of the highest-strength aluminum alloys available and has almost twice the strength of 6061-T6. While 7075-T6 costs more than 6061-T6, the strength-to-weight ratio of 7075-T6 makes it ideal for use on highly stressed parts. Both the upper and lower receivers on the BCM M4 Mod 3 are made from 7075-T6 aluminum forgings.
