Did not mount level on mac5, impossible to remove screws once installed - UTG Pro Extended Picatinny Claw Mount for MP5 / MP5K

I installed this rail on a MAC5. It did not seat level and cannot be adjusted as other mounts due to the nature of the claws that hold the mount to the firearm. I used an inch-lb. driver to install the mount and correctly torqued the screws. After determining that the mount could not be leveled, I began to remove it only to find that one of the screws had galled so badly in the claw that even with the application of heat it could not be removed. That process destroyed a pair of Torx bits. I finally managed to remove the remaining three screws, which allowed me to remove the mount from the firearm. From there, the mount went straight into the round file as it deserved, to be replaced with a quality MI mount. Lesson learned.

Bottom line: If you buy this and it doesn't seat level, good luck removing the mounting screws. Better yet, learn from my mistake and buy a better quality mount.
