So I have a Mossberg Persuader that I got just afew months back and I like it alot. I do however wanna put a tri rail forend on it so I got one from mako. Ive heard people having issues installing them but love them one they get them on. I am having a very difficult time getting into to slide all the way on the slide tube, it just seems to get stuck about a 1/4 inch to short. Does anybody have link to a detailed description about how everyone is getting passed this problem?
