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.

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

"So far I have had it for 2 weeks or so now and here is what I have seen while using it.

I was actually impressed with the weight, heavier than I thought it would be.
Being a NBB type I figured it would of been louder than it is.
I use duster gas and I get 280 fps at max, I will not use GG as I don't trust what anyone says about them being able to.
Range is decent, I was expecting better than any aeg.
On duster I don't get as many shots as everyone else does.
Pump handle wobbles but that is expected, What was not expected was the outer barrel wobbles a lot.
Buy TM shells, I bought some clone shells 6 months ago when I preordered this and got the chance to use them and they are trash, TM shells feed better and actually drop out of the gun when you open the shell door.
Dont ever use a sling on the provided sling mounts, the outer barrel wobbles enough that you will snap the gun in half.

I was expecting more out of "the great tokyo marui quality".
