This is by far and away the best offset rail I could find for mounting a reflex red dot as a secondary optic on my coyote gun (DPMS Oricale .223/556). I ordered numerous offset rails and ended up returning them because they didn’t give me the clearance I needed to mount the sight towards the rear of my weapon. This offset rail did just that, and provided me with sturdy high quality product that will ensure my secondary optic will hold it’s zero! Thank you Midwest Industries for making such a great product right here in the U.S.! If you’re looking to put secondary optics on your rifle this is the rail for you!!
