Things I liked:I needed good rings for my Weihrauch hw75 which has a 14 mm rail.
The BKL mounts fit the bill. After a few weeks of experience, I think they are almost perfect. Of course the HW75 does not have a strong recoil, if any, so the task was easy, but they did not move since I installed them and shot more than 500 pellets. Things I would have changed:Given that I am using them on a pistol I would have preferred them lighter. What others should know:Excellent construction, I highly recommend this mount.
