Love the american defense swing off mount. It holds solid as a rock and the swing action is awesome. Fast shipping and great value!!

overall good product


didn't realize this mount did a 180 degree turn, so the eye mag is backward when it is on the side. would like to see a flip to side mount

I love it.


Used this with 'PRIMARY ARMS 3X LER RED DOT MAGNIFIER GEN IV' - Works perfectly and lines up great with my Holosun HS503C. Several people at the range were like "Dude, what the heck is that - it's awesome!" - It really is :D. Since it rotates forward, you can still maintain field of vision/awareness. It does not obstruct peripheral vision.

Fast transitions


The flip to the side mount is living up to its worth ! I have it on a 10.5 inch AR 15 using Holosun 503ge ( I think ) but very cool red dot and a 3x primary arms magnifier that hangs out or in whether I’m using it ( pun totally intended) . It’s also kinda fun to mess with people not tuned up on all the goodies so I’ve told people , when the mount is in the open or not in use position, that it’s infrared or night vision. Great mount if you need one just buy it !
