I have a art morrison cage, I bought a s&w rear clip, If I do it again I would stay with a art morrison product. My S&W rear clip was not square, it was not a big deal to the guy that installed it, but another guy said he had same problem, I called S&W and manager said that the guy who builds the clip is also same guy who checks it out (quality control) and he said he had small company, and thats the way it is,not I am sorry or anything, said he will give me a good deal next time. Anyways wont buy from them again, I should have paid a few more hundred and bought from art morrison, never heard bad from them
