Because of the high demand, APS is now re-launching the MKI system, we call it CAM MK3. MK3 is an improved version of CAM870 MKI, it is still using push pin system, but internal is modified to make sure no real gun parts or shotshells could be used.
Hi there, looking for an aps cam870 MK1 or MK3, the gas in shells versions. I dont mind what model (as in wood stock, police model etc) so long as it is a full length shotgun style, but I would prefer the SAI version. For pricing, make me an offer based on model, condition and extra stuff include... Jul 09, 2014 · APS CAM870 Shell Ejecting Shotgun. Quite possibly the most realistic airsoft shotgun in the world, the APS M870 borrows from the APM50 Cartridge Ejecting Sniper RIfle and brings CQB to a whole other level. Unlike conventional airsoft shotguns, the CAM870’s power comes from the shells themselves rather than an internal gun reservoir or a spring. This isn’t entirely true. The APS CAM870 MK3 can also fire the shells from the original mk1 that use the wadding. I’d recommend the SMART shells that allow you to fill it with a 88g co2 cartridge, which use the wadding. You can also make your own wadding with a hole punch and thick paper, there’s some guides around here and YouTube I think.
