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 450 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.

I am a 75 YO Vietnam veteran. I like the real thing, I've had them, but the BB equivalent sure does fits the bill, and it reasonable to shoot. I also like the airsoft rifles and have quite a few.

Wow, this is a great product. I have the MP40 also and the M3 is much like it in how it functions. Pay attention to loading the magazine, do it one BB at a time and use good BBs, esp. the Umarex. Believe it or not, they are better than other brands and will save you a lot of time and frustration loading the magazine.

I don't know, I really like this item. I am 75 YO and still get a kick out of these items. The squirrels will tell you that they don't like them though.

I carried the real deal M3A1 .45 sub through Germany, Korea 1974-78 as an M601A1 and M551 crew member. Loved that crude lil shooter. THIS replica in .177 BBs is the closest Ive found to the real M3A1. Love love love the appearance and operation. You will not be disappointed. Buy with confidence.

Authentic appearance, authentic weight, authentic operation (single shot capability!).

No offer of a combo package: extra magazine, sling, and flash hider add-on.

Great gun at and reasonably price, plus fast shipping and great customer service.

The gun is an exact replica of the ones carried in Vietnam and would fool anyone who looked at it into thinking it was real. Heavy and well made with the look and feel of the original M3.

I wish the magazine held more BB's because it takes only about 17 seconds at full auto to empty it.

By HerbFebruary 21, 2023 Verified Purchase

Looks solid and built to last

Magazines seated too deeply into the gun so that it interfered with the function, was not able to use it at all..

By Mark MelansonFebruary 20, 2023 Verified Purchase

I had a recaptured grease gun in Viet Nam, never fired it in anger. I loved it. When I saw the Legends grease gun I had to have it. It weighs the same and it feels the same. I couldn't bring home mine from Nam but this is actually better. I can shoot it just about anywhere I want.

Should be gunmetal color and not black.

Great build quality. Feels, and weighs like what I'd expect from a real steel version. Hope to see more from Umarex. (Maybe an old school Ingram mac 10 ?)

By RandJanuary 28, 2023 Verified Purchase

Looks and feels like the original I had the opportunity to use many years ago. Also like the detent for the magazine follower, it makes reloading much easier, it should be included on the MP-40 mags.

Haven't had a chance to shoot it yet so can't think of anything. It would look more natural with a "weathered" finish

Does the magazine detach? If so can you buy extra magazines and load them?

asked Curtis from USA

Got my M-3, the gun works fine but the magazine does not feed well at all, tends to jam after one shot. I imagine other users have experienced this problem - any suggestions?

asked Douglas from USA

Hello, Zabby_do here. Is this "Legends M3 Grease Gun" made in China or Japan? Zab

asked Robert from USA

Does the screw on bottom of hand grip come off or unscrew like originals for the oilier. Thanks

asked Terry 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

Semper Fi from 1st Force Recon

Terry 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"

Timothy from USA

Is this gun are the real gun or just for game

asked John Griffin from Papua New Guinea

It's understandable I peop need to purchase an airgun for "pest control" , rat an the like but, just to shoot people or animals for fun, this gives arguments a bad name. We as airgun enthusiasts and collectors respect our airguns as real weapons. We handle our airguns in the same fashion as a real firearm. These are NOT toys. The can cause serious life threatening injuries to humans as well as animals. If a person wants to shoot as a toy, get "airsoft". However, even those should be handled safely and with respect. To buy an airgun inexperience can hurt yourself and others. No matter the firearm always learn about the gun and safe handling or, "you'll shoot your eye out kid"..

Walter from USA

Read description and the Specifications...They should always be read before purchase...

Walter from USA

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.
