ProWin M4 GBBR Mags & Ranger Plates
 

Hi there.

I am having some trouble removing the bottom mag plate on my ProWin M4 GBBR mags. I push down the little black "button" and try to slip the plate forward, but nothing moves. I have pushed really hard and still nothing.

Can someone please help me get these bottom plates off so I can install my USGI Magpul ranger plates please ;)

Thanks, much appreciated

like you said, push the little black pin, then lift the lip a little bit(with a flat screw driver) and slide, it should work.
Mine slides like that :P

As mentioned, you have to push the black-circle-buttom and lift/pull the plate with some force.
I was able to remove all the plates on my ProWins.

If you want to install Magpul USGI Ranger Plates, you have more mods to do ;)

I sanded the sides and wings off of the plastic plate lock and round the front corners to make it fit. Then I also sanded a bit of rubber off of the bottom of the rubber ranger-pull. Its a tough fit, but it works.

If anyone needs any help/tips on the Magpul USGI Ranger Plates , feel free to PM me or post here.
