APS CAM 870 MKIII Classic Short

Based on the Remington M870, a legendary shotgun that has been favored by law enforcement, the military, and civilian shooters around the world since its introduction in the 1950s.
The APS CAM870 series of airsoft shotguns are one of the most fun and realistic pump-action shotguns available, APS are one of the pioneers of practical shell ejecting airsoft shotguns.
This particular version is the short classic wood version (MKIII).
Used by cops of a bygone era across the world when simplicity & reliability was preferred over modularity.

The shotgun is exceptionally well-built and feels solid in hand, virtually no creaks or rattles.
The dense and robust feel is a result of metal construction with real wood furniture.
The shotgun runs off of the same CAM870 MKIII system which means it will use the same shells as that platform and can work with many of the same accessories.
Co2 is charged directly into each shell, shells are to be available separately here.
Holds 4 shells at a time & one in the chamber, each shell is ejected on each pumping action.
Satisfying smooth action and noise upon racking the pump.
Each shell is capable of holding up to 11 BBs at a time, range and accuracy is affected by the quantity inserted.
Stoppers or pieces of tissue can be used to plug the shells and hold bbs in place.
The more BBs you try to load into each shell at a time, the less power you get. We recommend keeping from 1-3 BBs per shell at a time for decent performance.
Simply load CO2 via the CO2 charger (sold separately) then load BBs into each shell, placing a stopper or piece of tissue to retain the bbs and then load the shells into the feed ramp on the underside, just like the real thing. Every time you cycle the pump handle, it ejects a chambered shell and rechambers another.
As this is a toy and the action is based on the real steel, jams and failures to eject are to be expected occasionally.
Extremely realistic action but power is a little limited and there is no adjustable hop-up so this is not suitable for skirmishing.
This model is not designed for heavy handed, continuous use like in weekly skirmishes. It is designed for light back yard plinking, collectors or as a showcase for authentic real steel operation in a quality replica.
We do not recommend this model for first time users or younger players.
Black in colour with real wood furniture.
Does not include shells or CO2 charger.
Wood grain finish can vary slightly on each model - some are darker than others.
APS smart charger & MKIII shells required for operation, available here.
