About the MKII System: The CAM870 Shotgun by APS has proven itself to be one of the most favored Airsoft shotguns on the market; revered for its realistic operation and construction, the APS CAM870 quickly became the go-to Airsoft shotgun for players looking for immersion. After listening to the feedback of Airsofters and industry professionals, APS went back to the drawing board to make the CAM870 even better.

The result is the CAM870 MKII. Identical in exterior design and build quality, the CAM870 MKII retains all of the hallmarks of the original CAM870 such as the pump action and shell ejecting action. APS however, has entirely redesigned the CAM870 gas system for the MKII system. Instead of using a complicated charging rig and having to charge each individual shotgun shell, the MKII gas system holds the gas in the bolt, requiring the user to only have to charge the bolt, reducing time spent loading and cost of shells. This convenient new system allows players to quickly top off their shotgun with a gas charge on the field with portable CO2 canisters (approximately 7-8 shots per full fill; 50~ shots off a single 88g CO2 canister).

"I love this shotgun! It’s absolutely ecstasy inducing when you rack the pump and load shells in. I noticed a slight resistance (the bolt would try to load the shell into the chamber but freeze halfway in a sort of jam, and require re-racking) but I honestly thing that’s just me, and not the gun’s fault. Honestly 5/5, absolutely wonderful piece of airsoft weaponry.


For the fore-end, Magpul Furniture comes with a tool that you’ll need to remove a lug to install the fore-end furniture. Pretty much a drop in fit. Get some hex tools and a screwdriver ready.

For the stock, I had a piece of round rubber covering a protruding tube where you screw a stock screw into. The rubber was not able to fit inside the plastic receiver bit that interfaces with the Magpul stock. I also found that the Magpul provided stock screw doesn’t fit with the SAI M870. You’ll need to buy a screw that does fit, or find a way to make it Interface.

"The other reviews are pretty spot on so I won’t expand on that too mich. I would, however, like to write some additional information for those out there considering a mk 3 engine swap and how to charge shells. The engine swap itself was easy, there are YouTube videos that detail how to strip down the gun. Make sure you get the aps fore end tool or find something that will serve the same purpose prior to performing the swap or you may be stuck halfway through the process.

Charging the mk. 3 shells (I bought some x-power shells) is pretty easy since the gun came with a charging nozzle but this method does not allow for adjustment of charge in your shells. If you want to adjust how hot your shells are shooting I found picking up a madbull charging nozzle (evike product id 31422) and then an adaptor to attach an 88g CO2 canister (look up “ 88g / 3oz Disposable CO2 Adapter - paintball” on Amazon and look for the “rap4” product, unfortunately it isn’t on evike) to said nozzle you end up getting a pretty solid setup that allows you to find tune how hot your gun shoots. I found anything over 800 psi and you risk blowing your orings in your shells so do with that information as you will.

Overall it’s pretty expensive to do the mk3 swap and all the mk3 APS parts need to come from overseas as evike does not carry them - they do carry the fore end tool, but none of the mk3 xpower shells, the xpower wads/covers, or the mk3 engine. I think this setup ended up costing me 1k (so far, I’ll always need the plastic wads and shell covers, CO2, I want to pick up more shells, etc., etc.). Lastly, I picked up all my parts from redwolf or tiger111hk, redwolf is legit, tiger was sketch but I got my stuff.

It’s a great setup and I had fun putting it all together, if you have the money, time, and, patience getting the mk3 setup is pretty awesome and really fun. People at my local field seemed to really enjoy it at the chrono range, not much out at the field though :)

"Straight out of the box BADDASS although my came with orange tip which I’ll remove later for custom upgrades also What it comes with is the shelll catcher , speed loading shells not the ones that need topples , upgrades or length adder (don’t know how to describe ) stuff that helps u choose comfertable length to it like stock adjustment or Quicker pump action ...other than that a sticker and nice box I got this 2020 so I recommended it
