About this creation
FPS! sight veiw actualy it fires rbs!
2 removable mags! WARNING: don't work lmfao
how mag release system works the tiny little pin is ther so when u push the 1x6 technic
connector that's attached to a 1x3 holed connector the tiny pin moves backwards
creating a space for that hole in the mag
when the mag is through the pin goes in the tiny little hole and doesn't allow the
mag to move
