"Very good QD mount. Easy to install and it comes with easy instructions and all parts needed, from tools to anti shock LocTite. Be sure to adjust the tension (instructions are supplied) to have a tight lock onto upper receiver. Also, be sure to zero scope if moving from carry handle mounting location to flat top, scope will be lowered. The locking arm has to be broken in and will be hard to unlock the first few times. Very nice mount for the price."

"American Defense makes one of the best QD mounts out there. It does not damage your rail like some and it is adjustable and holds the adjustment better than most. If I can get an American Defense for my application I do."
