Im sure there have been plenty of tops on this but i cant find any after going thru 3 pages of search result. But anyways I have a KWA m4 CQB with a CASV rail and the rail is loose. It shifts forward and back about 2 mm but its not just the rail but where it is mounted on the upper receiver of the body. Still shoots fine but i tried to figure out where i needed to tighten and no luck. Any suggestions?

did you take the upper receiver off and look above the charging handle spring? there might be screws there, if not, you could always put a bit of JB weld or super glue to hold it still

not yet ill give that a try
