    Make sure you clean/degrease the screws and holes before applying threadlocker. It's also a good idea to put witness marks on the screw heads so you can easily check if they're backing out.

    A properly fitted and installed clamp-on GB can be very strong, and if it's under a rail I wouldn't worry about it.
    The MFR has the bracket on the inside of the rear of the rail, which gives it much less clearance to fit over the gas block during installation.

    I guess some clarification. The MFR mounting ring will not fit over the gas block. You must slip the ring onto the barrel nut, install the gas block, mount the float tube to the mounting ring, then fasten the mounting ring to the barrel nut. Using this method the rail clears the JP block fine.

    If you spend much time around the guys who really, really know their craft, and who truly live this stuff, you tend to find that they are very soft-spoken and modest -- almost to the extreme. To my mind, that is a model worthy of emulation

    Assembled 4 with DD low profile clamp on GB's

    I have assembled 4 uppers 2 of which are SBR's based on BCM 11.5" lightweight barrels. Total round count is in excess of 10,000 rounds and there have been zero issues with these item(s.)

    I left about .035" clearance from the barrel shoulder at inception, and the feeler gauge still reads .035" for the space on my SBR. This is a very strong mounting solution.
