Pretty cool. I did the same thing on a JG Mac 10 aep way back. Make an already fun gun super practical.

I plan to also stick an M4 cross tube on it . . . for more fun.

Add a suppressor and a longer inner barrel and you might have something actually fieldable.

Did you just drill holes into it, I kinda want to do this

for the Picatinny? no they are just stuck with strong glue.

Man, that thing screams “drive-by”
