Spare Magazine Butt Plate for WE / KJW / Tokyo Marui Hi-Capa series Airsoft Gas Blowback

"I was playing an intense game of CQB and while I was running I dropped my WE-Tech Hi Capa 5.1 T-Rex pistol (it wasn't properly secured on my belt). When the pistol fell the mag went flying out which consequently sent the butt plate flying. I can't remember if it broke or what happened to it but I had to replace it. This new one has a much nicer finish, a bit on the matte side and it's much lower profile. I prefer this one over the stock one that came with the pistol. I'm actually thinking about buying replacements for all my mags.
