I purchased this rail mount to add some accessories to my Mini 14. While impressed with its solid construction I initially found that one of the threaded holes for the rear set screw had a burr which was easily defeated with a couple of turns of a tap. Installation took all of 15 minutes. (I'm a slow reader) After mounting a Trijicon Reflex and Nite Hunter 500 NHT 500 light it was time to head to the range. Several reviews indicated that the mount tended to loosen after firing live ammunition but that was not the case with me. After 200 rounds the mount remains solid. I highly recommend this product.
Pros: Simple installation - Retains Zero
