Laylax Polymer 5 Round Shotshell Caddy for Tokyo Marui KSG Airsoft Shotguns

"It's a great shell holder for any shotgun, just use Tokyo marui shells for the best fit. The back plate is metal and the rings the hold the shells are polymer, speaking of the rings, they can be changed to be angled at a 45 degree angle, but when you do that you sacrifice the ability the hold a 5th shell. Overall it's a nice shell holder with top notch Japanese quality and can be mounted to any shotgun really if you use some creativity, I mounted it to my Tokyo Marui Spas 12.
