Bravo Company builds:  Life Saving Tools™
 
Manufactured by Bravo Company MFG, Inc. (BCM)
These Barreled Upper Receiver Groups are designed for shooting professionals and responsible civilians with the Mil-Spec features for the demands of their duty. They are fully assembled, headspaced, and test fired.
 
 
As a note: Prior to shipping, all BCM upper receiver groups are test fired for function, laser bore sighted with a Milspec carry handle for sight alignment within Mil-Specs, and then batch samples are test fired for accuracy. As such, the upper receiver group will show handling marks consistent with these quality control procedures.
 

SS410 Barrel Steel
This 16" BCM barrel is machined from SS410 stainless steel. Featuring hand lapped 1/8 twist rate button rifling and M4 feed ramps barrel extensions, the 410 stainless barrel gives the shooter the best balance of weight and accuracy. 410 stainless is also harder and more corrosion resistant than conventional 416 stainless found in other commercially available precision barrels.
 
 
M4 Feed Ramp Barrel Extension and Upper Receiver
In developing the USGI M4 carbine as one of the primary weapons for today's infantry, some modifications were performed to the original M16 platform to enhance the reliability of the shorter barreled carbines. With the shorter carbine gas system and the increased gas port pressure, the carbine cycled faster, and at times the cycle rate could be faster than the magazine would feed ammunition. One of the modifications done to increase reliable feeding included enhancing the angle and the length of the feed ramps. This USGI modification was done to both the barrel extension and the upper receiver, creating a longer and steeper feed ramp. These Mil-Spec M4 feed ramps are part of the original CNC manufacturing process. As a result, the factory machined M4 feed ramps on the receiver are hard coat anodized which adds significant strength to the aluminum. This feature is offered on all BCM upper receivers and all BCM barrels.
 
 
T-Marked Upper Receiver
The contemporary M16/M4 rifle is built around the concept of modularity. All of the BCM flat top uppers feature a USGI type laser etched T-marks to provide addressing for the remounting of tactical accessories such as optics, laser sights, etc. This enables the weapon platform to be easily configured and then accurately reconfigured for each specific mission.
 
 
5.56 NATO Match Chamber (USMC SAM-R Chamber)
The USGI 5.56 NATO chamber is the best choice for effective deployment, reliability, and compatibility, of higher chamber pressures of military or high quality personal defense ammounition.  The SAM-R chamber is the precision version of the 556 NATO chamber.

    BEYOND IMPRESSED

    Posted by jonardl on Dec 28th 2016

    I paired this upper with a complete BCM Lower. Yes paired since I couldn't find a complete setup with Ionbond BLACK barrel.

    This is my first BCM rifle and I am BEYOND IMPRESSED. The fit and finish is exceptional. For a 16" setup it is very light even with a 1-4X scope and is still lighter than my duty setup.

    Bolt carrier group

    Posted by zachary rice on Dec 28th 2016

    I bought the complete upper with the BCM bolt carrier and charging handle. Simple to attach to my Spikes lower receiver and seems to fit well. The only problem I have is where the bolt carrier group hits the buffer tube, there's a very small piece of metal that is sticking out. I didn't notice this until after i cycled a few rounds through it. Now I have to replace the buffer tube and file down or sand that piece of metal on the bolt carrier group.

    You get what you pay for

    Posted by Chris on Sep 22nd 2016

    I purchased this upper as a complete assembly less charging handle. This is my first BCM, but not my first ''top tier'' build. The materials and finish are of excellent quality, and considering it's a stainless barrel, it's very light.

    More importantly, it's very accurate. I have only taken it to the range once so far to break in the barrel, and it was depositing XM193 into a 1.25 inch group at 100 yards using Nightforce glass. At this point, I'm very interested to see what it will do with match grade ammunition seeing as how it's already near MOA with milsurp ammo from the 90's.

    BCM of course shipped the upper well packaged and with several BCM goodies. Shipping time was quick, too. Thanks for the deal, guys!

    Best bang for your buck, $ for $ bar none!

    Posted by Tracy on Sep 22nd 2016

    Bravo truly makes some of the best products dollar for dollar without exception. Having been in this field for many years it's truly amazing what you get for the cost. I have ordered many different products and gear from Bravo and I am always pleased with the fit, finish and function of every part I've ever ordered. Their quality is exceptional, customer service is superior and accuracy exceptional, because of this I continue to return to Bravo for all my tactical needs!

    Outstanding Upper!

    Posted by Dave on Sep 22nd 2016

    This upper receiver group lives up to the hype. Very accurate with my 55, 62, and 75 grain ammunition, producing 10-shot groups under 2 inches at 100 yards with all three loads, and the first 5 62 grain rounds went into a ragged hole 0.5 inches across. Buy with confidence.

    Glad I went with Stainless Ion/KMR Alpha

    Posted by Nichols on Apr 26th 2016

    Very nice barrel, shooting under two inch groups at 100 yds. using a red dot first time out to the range. The receiver group functions flawlessly and the KMR Alpha is very light weight. I'm 100% satisfied. BCM has been great to deal with from customer service to super fast shipping, a top notch company.
