"Black Hills Ammunition has been making the most accurate and lethal 5.56 cartridges for years. In particular, their 77 grain OTM or MK 262 variants as its known in the military has performed without fail for over 20 years. I have used it myself and consider it lifesaving equipment.
As a military sniper I came into service when BH 77 grain was gaining favor with my community and also when my community began the concept of what's now known as the MK 12 5.56 light sniper rifle.
Over the years and through many rounds, testing and evaluations I, along with others, discovered that a twist rate of 1/7.7 is the absolute best for optimizing performance from Black Hills 77 grain ammunition. Now thanks to BCM® anyone can buy a complete upper tailor made for use with BH 77 grain variants."

    KD4 upper

    Posted by Tyler P. on Apr 9th 2019

    The BCM rails are a great profile and the 1:7.7” barrel shoots excellent. Through the first 400 rounds every group on paper has been sub-MOA with the 77 gr Sierra bullet. I’ve only shot it to 300 so far, but the rifle is maintaining 2.5” groups at that range. I couldn’t ask for a better upper in terms of weight, handling, and precision!

    Outstanding upper

    Posted by Joshua Anderson on Dec 18th 2018

    Had this upper for about 6 months now well over 1k rounds, no malfunctions, smooth shooter and very very accurate. 400-600 all day long. Ive even been able to hit a 1000 yard target with this upper (may have been luck). If you are thinking about buying this upper stop thinking and just do it, you wont regret it!

    Great upper

    Posted by paul lee on Apr 17th 2018

    Quick delivery and great quality from BCM again.
    I placed this upper onto my BCM lower and hit the range. Zeroing it in, I was struggling to tell if I was getting hits while my buddy on the spotting scope kept telling me he could only see one hole.
    There was a reason for that.
    When we walked up to check the target, all 5 shots were in one ragged hole.
    Great quality, just what I've come to expect from Bravo Company.
