I need some advice from the experts on this forum, I have a CZ 457 MTR with a 419 rail with a Arken scope, after about 100 or so rounds I noticed the scope and rail moved forward, I removed the scope and used blue locktite on the rail screws and let it sit over night, but it happened again, should I get rid of the rail,if so what do I replace it with. My shooting range is 100yds,do I need the rail? Any advice is welcomed
