If you don’t, a qualified gunsmith should handle the job for you.

I found installation of the KMR to be easy enough assuming you have all the right tools. When I emailed Tex300BLK to tell him I had the KMR inbound, he told me that installation was fairly straightforward, but like anything, go slow and take your time.

The full kit including rail and mounting hardware weighs in at 7.6 oz. pure aluminum without sacrificing strength. Folks looking for a lightweight build should surely have their ears perking up at this point.īCM indicates that they’re able to get such a lightweight 13″ hand guard by using an aluminum and magnesium alloy that sheds 30-40% of weight vs. Keep in mind that my test unit was a 13-inch version and that BCM offers 9- and 10-inch versiona as well for those looking to shave even more weight. The rail alone without hardware weighs 5.35 oz. And sure enough, upon initial inspection, the first thing you notice is how darn light the rail is. Billed as being invented by the “Father of KeyMod”, BCM claims that the KMR is light, tough, and strong.
