Tokyo Marui never ceases to amaze with their innovative new designs and improvements in the airsoft world. Once again, they manage to bring us a product which will set the standard to what future guns will be measured with. The all new M870 full metal gas operated pump action shotgun combines realism with convenience for those looking to utilize a shotgun for CQB skirmishing. This innovative new shotgun has multi shot capability allowing for multiple BBs to be discharged with one pull of the trigger; with a quick flip of a switch, the M870 can switch between 3 and 6 BBs discharged with each shot. Until now, shooting more than 3 BBs at a time was reserved only for shell ejecting shotguns; the M870 however uses the same shells as the original TM shotguns as well as the UTG spring shotguns making it easier to keep track of your shells and with the added advantage of having more ammo per shell. The gas operated system allows for a smooth racking action compared to spring powered shotguns to allow for rapid follow up shots and unrivaled speed. Last but not least, lets not forget distinct and satisfying sound of a pump action shotgun being racked.

"Probably the most quality shotgun replica I have had the pleasure of using on the field. It's very accurate, feeds reliably, and it even SLAM FIRES (slam firing is when a shotgun fires immediately after racking if the trigger is being held in the pulled position). I consistently outkill AEG users on my local field with this thing, and now my only concern is the shot shells themselves. They are quality and feed well, and are also easy to reload. My problem is that they are 22.50 for two shells. This is downright robbery when Evike sells the Zombie Stopper shells, which are more or less identical, but are only 5-6 bucks for a pair. Overall, still a phenomenal shotgun.

I ordered this with a plethora of other accessories, and it actually came! I was sad when I saw that they pushed the preorder from April to May, but then I got it, and holy Jebus was it amazing!

The best part was that Tokyo Marui put a thin blue ribbon around it, and a small blue bow tied on the top. I laughed for five straight minutes. This is by far the greatest airsoft order I've ever made. Ever.

The gun isn't a lemon!

It's a phenomenal replica! Some say they've gotten wobbly outer barrels and that it's unstable, but by damn this thing is perfect.

I haven't fired it yet, but rest assured, I'll only be using duster gas, NOT HFC134A!!!

Nice and heavy (pro for some, con for others)
Uses UTG shells, probably...?
blah blah blah, everything positive about this gun is true.

If you think there are cons to this gun..... you're a dingus.

"I've fired this weapon a few times and what I have learned is that it is extremely reliable. It also shoots at very good accuracy and range. Another thing is that with aegs and spring snipers, you feel a slight amount of kick, this thing has absolutely nothing at all; It's like dry firing it but it shoots. This is especially good at scaring referees at Mr. Paintball
