Really good ergonomics and weight. - Bravo Company KMR Alpha KeyMod Free Float Handguard

I own three BCM rails. One 15” KMR, one 15” MCMR and one 9” MCMR. The guy complaining about the 0.4” is ridiculous. The measurement is the pic rail section. You can clearly see that the sides go a bit more so if you are trying to run exactly 15” so you can get a suppressor mounted and get it right up to the rail you will waiter need to cut the wings off the rail or get a longer barrel. Or buy a mount that pushes out a bit further like a HUB mount that has a longer nut. The pictures show the rail, the dimensions are available. Do your research and pick your parts more carefully. Don’t blame a fantastic company with a great track record and product for your own lack of research. Also if you don’t own a dye grinder or know how to trim the rail wings you probably should not be building firearms. Get the tools so you don’t act a fool. BCM handguards are great quality and at a reasonable price. If you want a 10.5” barrel get the 9” rail, if you want a 9” barrel get an 8” rail. Simple.
