    BCM KMR is WEAK sauce!

    So I'm no longer a fan of the BCM KMR, the original magnesium variant as I have no experience with the Alpha.

    Why? Because it is super weak sauce.

    The firearm was leaning against a wall, unloaded, on a rug carpet. It fell over. It landed on the front offset iron sight, which is a Griffin Armament. Ultimately a VERY low impact event.

    Here is how well the KMR DIDN'T handle it.

    And here is the front sight, which is what took the impact, and still looks new out of the wrapper.

    Seriously? This is unacceptable. A front sight can no longer be utilized at the front of the forend anymore with any ghost of a hope of being aligned with a rear, and that's from simply falling over on a rug.

    I'll will be contacting BCM about this and will report with how it pans out.

    There are more than a few reports similar to this. The alpha is superior in every way except weight. I'm sure BCM will take care of you.

    I have already deformed a couple magnesium KMRs during destructive testing. The alpha is stronger and more rigid.

    Mg just isn't strong in that thin of a structure. That lesson has been learned.

    That sucks a lot. Seriously.

    Here's to hoping that they do right.

    I'd be pretty shocked if they don't make things right.

    Second this. What amazes me is why they even tried it in the first place with all the knowledge from the motorcycle and aerospace industries alone.

    Because everyone loves BCM......!? The fact that they tried it and sold it to the consumer given said prior knowledge says a lot.

    Well, now you don't need an offset front sight.

    You know, I knew the magnesium alloy was weaker than aluminum, but not being in the motorcycle world or ever having really worked with magnesium, and given BCM's rep for good stuff, I really thought that the alloy would at least APPROACH the strength of aluminum.

    Guess not.

    I've already emailed BCM and sent along all the pics I've posted here.
