It looks like Bruce had some fun in using the APS APM50 with its shell ejecting feature in this BB2K Airsoft video review... "The APM50 from APS is a CO2 Shell Eject airsoft rifle which make a lot of fun. The function is similar to the APS CAM870 airsoft shotgun. Each shell is individually filled with CO2 and equipped with a BB. There is space for 6 cartridges in the box magazine. Depending on the shells, the power ranges between 1.5 - 6.0 joules.

Due to the system, this rifle is not exactly suitable for airsoft play, despite the shell catch bag. The shells are expensive, there is no hop-up and the maintenance of the rifle or shell is high. The collector and tin shooter is rewarded with a lot of fun and realism."
