Oil in Retro Valve, Need help

[warrior18]

Hey guys. I just bought a Retro Mag with z-grip the other day from a guy and when I looked at it it wasn't cleaned or lubed properly. When I asked him what he did he said he put oil in the back of the valve. I just want to know is this gonna hurt my mag and what should I do to it to clean it out cause I know you are supposed to use grease for it?? Thanks

Grease only goes on the velocity spring pack and threads.

For the rest of internals just put a few drops of oil in the ASA and cycle a few times without the barrel on.

Putting oil in the back won't hurt it. Do what potato boy said from now on. The only thing that could have happend as a result of his oiling was that he shot some into the barrel. All you would need to do is clean the barrel, dryfrire a few times with no barrel, and its fine.
