Looks great, but doesn't hold zero - Scalarworks LEAP/14 Quick-detach Red Dot Sight Mount

Despite being tightened down as much as I can get (with gloved hands), this will not hold zero. I have a laser. At a fixed distance (e.g., a target at 50 yd at my local range), I can apply lateral pressure to the ACOG and get my crosshairs to move laterally relative to my laser. Not great. This doesn't happen with the stock mount. I have several Scalarworks Aimpoint mounts and a scope mount, and they've all been great. Like those, this mount *looks* fantastic. But I need one that works beyond CQB distances.
