rail bushing & leak

[temps]

my mag was leaking down the barrel. and after checking the orings and everything looked good i was puzzeled.. then I read somewhere that the rail bushing is there for tolerence issues, and i took mine out over the christmas holiday (working on putting on 03 shocker frame on the mag) and then i put it back in and the leak stoped.

So is it possible that the missing rail bushing was causing the leaks down the barrel?? I assume it was the problem as when i put it back in the mag was happy again. Just would like to verify this conclusion thx :)

Not having the rail bushing was your problem. When the bushing isn't there, it allows the valve/bolt assembly to move to the rear, which doesn't allow the bolt to seal properly.
