CQC SERPA Tactical Drop Leg Holster Platform Panel Plate Tan
[AS1467]

This thing is a great buy for any airsofter the color is good and it will adjust to any size.
There are a couple of cons to it though:
The belt mounts will start to make a weird sound that is fixed by adding tape.
The platform may interfere with your knees movement.
Finally its hard to reach the bottom screw when you mount your SERPA.
