    A few years ago I picked up a Troy MRX rail at a gun show and had a smith install it and all was good. Then I added a foregrip and the bottom piece of the rail started sliding out. The bottom rail needs some force to move, maybe about ten pounds of force. Anytime I leave my left hand on the grip and try to manipulate the charging handle it will slide out though.

    Is this normal? Did I get a defective rail? Should there be a pin to go in the hole on the bottom rail just forward of the magwell?

    Thanks,
    DSMonsta

    I think you mean MRF rail? If so, then when you look at the bottom of the rail just forward of the mag rail, there should be 5 screws. 2 on each side, and one in the middle. If the one in the middle is missing, the bottom rail will slide forward about 1/2", and then if you pull down on it, it will separate from the top section.

    I have two screws on each side and an empty hole in the middle I suspect that's my problem. Thanks Nevermore.

    There used to be a model with a spring loaded button in that location.
    Check Troy Industries' website. They have product manuals in the "Tech notes"

    I think that I may have one of the early models that are spring loaded as the fifth hold at the base of the rail isn't threaded. Thanks faawrenchbndr.

    I thought they were removable for the launcher to be attached.
