Halfway meets expectations - OpticsPlanet Exclusive Kinetic Development Group SIDELOK Aimpoint Micro Mount Lower 1/3 Co-Witness

The company website, as well as the photos on OP show holes, mine did not have holes drilled all the way through, ultimately this doesn't effect the performance, but it speaks to quality control. The packaging also claims the screws come with thread locker on them, they did not. Again not a hard fix. Finally, this is my biggest complaint by far, is the way the locking mechanism operates. No matter how hard I tried, I wasn't able to get the mount to lock to my upper receiver, but it did lock as expected to the rail on the handguard. Hard to say if that's a problem with the mount or my upper. I probably need to test it on some other pic rails. Overall I think it'll get the job done for now, I can make it work, but I probably wouldn't suggest this to another buyer. I honestly expected far better quality for the price they ask. I probably would have been just as well off paying 2/3 the price for something less complicated off eBay.
