I love my two BCM KMR's (one mag, one aluminum), I also have two other Keymod uppers and one M-LOK so Keymod is winning in my house. To switch everything to M-LOK would be several hundred dollars, so not anytime soon, especially when Keymod works just fine. Maybe if BCM does make the M-LOK KMR then I would consider, I love my BCM setups.
