Rear receiver pin backing out
Hi folks,
I just recently purchased a KAC SR15E3 Mod 1 carbine, which is my first AR. My experience & knowledge with AR's is definitely lacking compared to the folks here at m4carbine.net, so I figured I would ask here about a potential issue with the rifle.
First off, I would just like to say the rifle so far has exceeded my expectations. The fit and finish is incredible, the rifle is definitely quality. It is light and points extremely well, and is a really soft shooter. I have put a t1 micro w/larue qd mount, magpul ctr stock, miad grip and vickers vcas sling on the rifle.
The only potential issue I have so far with the rifle is with the rear receiver pin. The pin seems to walk out on its own, if that makes since. I can literally shake the pin out of the rifle, which doesn't seem right for a battle ready rifle.
The only thing that I could think of, is that while installing the magpul MIAD grip I might have screwed something up. There appears to be a spring/pin in the lower that holds the receiver pin in place, maybe after installing the new grip this part got messed up. I'm not sure if this is making any sense, I'm having a hard time explaining it. I can take pictures if this will make it any more clear.
Anyways, if someone has any suggestions please let me know. I assume this is not normal, but maybe it is?
Thanks in advanced.
