  1. Christopher Mulholland (verified owner) –

    I got this to mount my shiny, new Gen 3 Razor, and I wasn’t disappointed. Scalarworks, as usual, included all the parts, tools, and the installation was idiot-proof. I can’t tell if the LevelDrive tool is an improvement over the older LEAP screw, but since I’m trying to save weight on this build, every bit helps. I also purchased a KICK/06 for use with this mount, and everything fits together absolutely seamlessly.
    After roughly 650 rounds (77gr, 16″ barrel, healthy mix of suppressed and not), there hasn’t been any shift, loss of zero, or loosening of screws. This is definitely a great upgrade!
