There are lots of ways to customise the Action Army AAP-01 Gas Blowback Pistol. For those who want a carbine conversion, there are kits available such as the Flintlock Custom Workshop Monster Carbine Kit and a 3D Printed Action Army AAP-01 Carbine Kit by Radex 141. There is a kit available in Japan and Mach Sakai goes voer one if it gives him the satisfaction to use in a steel challenge.

A compact GBB that can be fun to shoot with, Mach Sakai checks out the Maruzen Škorpion vz. 61 GBB machine pistol if it is something he can bring for his steel challenge practices, checking its operation and performance. This has realistic field stripping and functional decocking lever. Gas magazine capacity is 30 BBs.

If you want to capture the airsoft sniping action via the scope, here is one way of mounting a smartphone to the scope. Mach Sakai reviews this product that can be ordered at Amazon.jp. With smartphones' videos now at full HD or 4K resolutions, you can capture high quality videos without needing any other action cam if you are on a budget. We would recommend this for DMRs rather than bolt-action rifles as it tends to get in the way when you pull bolt.
