VFC / ELITE FORCE / UMAREX UMP GBBR RECOIL RS BUFFER SPACER

Original files were designed by Roni_Industries, I just modified it for ease of access for others. This is a 10mm spacer designed for the VFC UMP45 when using a real USC/UMP buffer. Place this inside the backplate before pushing the buffer ontop. I strongly recommend using hot glue or some kind of filling adhesive to secure everything.
