I have a G&G R5. I noticed the upper portion (upper receiver) of the metal body is a little loose not by much but just enough to affect the feeding of the bbs from the mags. I have to play with the mag in order for it to feed properly. If anyone can share some info to see if somebody out there has experience this problem, I'd appreciate it. Thanks.

Here is what I found out on my R5. Due to my 203 which makes the front of the rifle a lot heavier, the stress point of the rifle is in the middle of it which caused the upper receiver to come loose. I ordered ordered a special pin from Bushmaster to help it stabilize other wise, I might have to change my metal receiver which would cost me more. If any has any suggestions please reply. Thanks.
