The Legends M3 Grease Gun takes a classic .45 cal warfighting submachine gun and turns it into an incredibly authentic airgun copy that gives you almost identical look and feel when compared to the original. It's based on the later M3A1 variation and let you shoot at speeds up to 415 fps with a rate of fire of 1025 BBs per minute, so you can experience what these guns are like without having to go through the expense and hassle of trying to find a real steel model.

One of the first things you'll look for if you're an enthusiast is the flip open dust cover and the hole in the bolt that you use to cock it, and both of those features are included on this airgun. That's the main upgrade over the original M3, and it means you don't have to worry about a crank cocking lever.

With this version, you just put your thumb in the hole to cock the bolt, and then either hold the trigger down, or pull it as fast as you want, depending on whether you have it set to full auto or semi auto. Plus, the gun features blowback action, a drop free stick magazine, and a collapsible wire stock to give you a look and feel that's very close to the original version.

This airgun uses two 12 gram CO2 cartridges, and you'll get to shoot about 120 BBs (4 magazines) on fresh cartridges. For sights, the Grease Gun uses a fixed blade front sight and a fixed peep style rear sight.

If you want to find out what it's like to use a gun from history in an affordable full metal CO2 version with the same features as the firearm model, get a Legends M3 Grease Gun at Airgun Depot Now.

When is available?

asked Lee from USA

How and at what shop can I find the correct sling? (NOTE. I was issued one in Force Recon, USMC)

asked Force Recon-USMC from USA

M1 Carbine sling was what was initially issued per my research (along with the same oiler in the handle for this model - unsure if the Umarex allows access - on the side for the earlier model that had the cocking handle). They can be ordered on a ton of places online - run a search like "m1 carbine sling for sale"

Is this gun are the real gun or just for game

asked John Griffin from Papua New Guinea

You forgot about the part; ...."and you'll shoot your eye out ! "


This is a .177 caliber bb gun, it is used for shooting targets only. Shooting people or animals with this would be cruel, it would hurt small animals severely and cause significant pain, the same goes for people.
