Airsoft Mike is back at it again, finally replacing a broken shotgun from years ago with two shiny new toys: the APS CAM870 Mark II and Mark III. Whilst they look like twins on the outside with their fancy wood stocks and metal bodies, they have very different personalities when it comes to eating CO2.

With the release of the second generation of the APS CAM870 Series, which started the realistic airsoft shotgun production, APS have released videos to help owners of the CO2 airsoft shotgun, and here is a video on how to change the bolt of both the MKI and MKII versions.
