    Cross Bolts

    These are small and light, but they're built to last, and to stay tight due to the indexed positions on the shorter of the two cross-bolts.

    Direct replacement

    I was in a rush reassembling my rig and stripped one of the cross screws. Perfect fit and finish on replacement parts.

    BCM KMR Crossbolt Kit

    Absolutely perfect item, just as every BCM item I own. I misplaced the original bolt set and had to order another in order to find the originals.

    Love bcm/kmr System

    Best free floating handrail system IMO. I have them on every rifles/ar pistols I own. Easy install/removal. It’s too bad I don’t have a patch for having 9 of them
