Backdraft explains how he built a full auto airsoft shotgun in this video... "This shotgun was a blast to build, and I'm super excited to use it on a field. It's mainly designed for cqb, but the range that it receives can make it a devastating gun to be up against outdoors as well.

A consistent volley of bbs, 3 at a time, will be hard to dodge for sure, and I doube anyone will be very happy when they get hit with it.

Backdraft installed an HPA engine on a rather very cheap airsoft springer. Did it improve in performance? Watch the video... "HPA engine in an $11 springer? yes please. Today I made a ukarms springer into an absolute noob slaying beast. Also, its technically bullpup so screw you guys."
