SRU PDW Carbine Kit with Elite Force Glock 18C Full Auto. Select fire semi and fully automatic fire modes. 300-320 FPS Green gas blowback Elite Force Glock 18 fitted inside an SRU PDW Carbine kit. The kit has a adjustable stock, Rail mounts (2 on both side, 1 on top and 1 on bottom), Storage space for an extra mag and comfortable, Sleek design. It’s pretty loud and shoots really fast. The Elite Force Glock 18C has a metal slide with a polymer grip. The Carbine Kit is made out of 3D printed polymer. I used this gun a few times and when I mean a few time I mean I only shot it around the house and in my backyard probably 5 or 6 times. There’s nothing wrong with it and it works great. The only thing is that the charging handle for the carbine kit rattles a bit but it doesn’t affect anything and that’s how it came when I got it. Any questions feel free to ask. No trades.
