From Service Members worldwide to the prohibition era gangsters in Chicago, the M1A1 is just as famous as it is infamous. This Umarex Legends replica steel BB version is dead ringer for the original "Chicago Typewriter". Utilizing a 30 round stick magazine that fits two 12 gram CO2 cartridges, the M1A1 can send rounds downrange at velocities of up to 435 fps and it does so with a very realistic blowback action. The M1A1 can be shot in semi-auto or full-auto, giving you hours of fun plinking in the backyard. This rifle has faux wood furniture, functional sights, and sling mounts that add to it's surprisingly realistic design. The Legends lineup from Umarex has delivered on another replica that is historically significant and well designed once again!

Can’t say enough about how much I like this gun. No problems at all.

Best full auto I own. Shoots very accurate on single and full auto. I get two + mags with the two co2 cartridges


By MikeUSAAugust 4, 2020

Made a detent for the mag from an old bucket handle, bent so one end is secure in the allen fitting, other end holding the detent. Coulda made one from a coat hanger. Put BBs in one of those restaurant mustard containers, cut the tip at an angle, Have loading down to 5 seconds

Surprisingly accurate in single fire

was a pain to load

By JasonUSAJuly 6, 2020

stock up on co2 they have good deals on this site if u buy in bulk get the 100 count great value

this gun is awesome iv never seen anything like it iv got a lot of guns off this sight but nun are more fun to shoot this is extremely accurate on full auto and it is loud i made a shooting range in my closet to catch bbs and can’t shoot this all the time for fear of my neighbors hearing but it is closest to real thing imaginable must have to all full auto collectors my recommendations to everyone

wish they had extra magazines run out in milliseconds

The fit & finish is excellent. And Airgun Depot had fast delivery & great customer service.

Having owned several old .45 Thompson’s & M1A1s previously I was surprised at the quality & almost exact copy of these compared to center fire guns. The fun factor is priceless. BBs are almost free & 3 mags per 2CO2 cartridges works out to about 1/2 cent/shot so the operation cost is negligible compared to .45 ACP cartridges. The hollow stock, although very authentic looking, sounds funky. I took the butt plate off & filled it with wood putty. No hollow sound now & improves the balance. The mag follower is a PITA as everyone says but there is an easy solution. I used about a 3 1/3 inch long x 1/8” diameter steel rod & flattened both ends with a hammer. Then bent both ends 90 degrees so that I could use it to push the mag follower back & hold it in place hands free while loading BBS. Lowe’s or Home Depot or any welding shop has those steel rods. Can send pix to anyone’s email if they PM me. [email protected]

None. Good thing these weren’t available when I was a kid. I would likely still be in jail now.

Find a tiny paint funnel in the model aisle of your local Hobby Lobby. Use it to hold open the mag follower while pouring in BBs. Far fewer tiny metal balls will fall on the ground!

I owned an actual M1A1 Tommy gun for a few years (semi-auto) and fired full-auto models at ranges. I can say with conviction that the Umarex is as close to the real deal as an airgun could get! The weight is close enough (within about 2 lbs) to feel authentic. The plastic stocks are quite good. And the rear sight, despite others' complaints, is the same crappy piece of folded metal mounted on the real thing. My papa shot the locks off the gates of a Kamp in Germany with his Tommy in 1945. I might buy him this for his 95th birthday.

Rate of fire is too high (about 2x the actual; more like a Schmeisser.) Ought to come with a tool to make it easier to hold the follower down while reloading. Extra mags would be helpful.

For the money I expected a little more quality. Also I expected more to come with it. Maybe a cleaning kit, sling or a rod to unjam BBs

It has good weight and looks incredible

The pistol grip and forgrip are a little loose and wobble. I've tried tightening the screws but it doesn't work.

This gun is awesome so far. I have put about 900-1000 rounds through it with zero malfunctions. I get about 150 shots (5 full mags) before the it runs low on gas, which I feel is reasonable. It has decent power and decent accuracy for a BB gun. I added a WWII reproduction Kerr sling which looks perfect and works like a charm. If this does not put a smile on the face of the shooter, nothing will.

Size, weight, attention to detail, select fire capability, open bolt firing

The hollow plastic butt stock LOOKS good but it is a dead giveaway that this is not the real deal. I may try filling it with something? (If the butt stock was not hollow sounding it would be a great improvement. I wish the cyclic firing rate was slower. This thing fires VERY quickly on full auto. I can live with both though.

By garyUSAJune 4, 2020

Great gun at first bought an extra mag fired both 5 times each was getting 6- 7 reloads for each load of CO2

Yes it needs a lock down on the detente really tears up the fingernail but biggest issue now is after 1 or 2 loads in a mag it freezes up and you are done for the day . Not sure why this is happening I sent it back to Umarex and they test fired it with 3 mag loads and did not see the problem . So here I am again with both mags not functional . I fire in auto short bursts to dump 30 bbs in @ 15-20 seconds. I have the Legends MP40 and do the same with 52 BBs and have never seen this problem yes I fire it the same way

I was worried that the plastic stocks would make this feel like a toy but I was very pleased when they did not! Sure, you can tell its not wood from the feel of them but they don't sound hollow and they don't flex. They do their job just fine and look great. I can tell you the weight difference between the real Thompson and this BB gun Thompson is significant but then thank goodness it is! The real one is one heavy son-of-a-gun! I do believe the cyclic rate is higher than a normal Thompson but it sounds really cool! I am pleased as I can be with this BB Thompson!

I like that the CO2 is incorporated into the magazine along with the BBs. This helps with realism and makes the gun completely safe when the magazine is removed. No BBs, no gas. Safe. The selector switches (Fire/Safe, Full Auto/Semi-Auto) are nice and the magazine release is fairly true to the real McCoy.

The magazine follower is way more difficult than it needs to be. This seems to be the norm with most full auto magazines... A tiny slotted follower you are supposed to slide back with your finger and hold until you can fill the column with BBs. It's much too small for just the pad of your finger so you use your fingernail. The spring is smooth but fairly tough too. You can count on wrecking your fingernail a few times and spilling BBs all over the place. The rear sight is a far departure from a real Thompson but will do just fine.

Will they ever make a drum type mag for this item or design a similar Tommy gun.

asked Derrel from USA

Umarex Legends M1A1 BB Rifle magazine CO2 question. Does it actually operate on two CO2 cartridges or just one? Read the instructions and information on both this page and Umarex website as well as comments/reviews it's not clear. I just received my new M1A1 and inserted two CO2 carts. When it was empty and I remove the CO2 only one cartridge had been punctured. Can someone provide clarification please? Thanks, kw

asked Kenny from USA

need new o-rings for the magazine , the one that goes on the end cap for the c-o2 the one is bad and needs to be replaced for the m1a1

asked floyd from USA

For parts contact Umarex USA 479-646-4210

Mark from USA

Will this accept the drum magazine from the 1928 model?

asked Gary from USA


Mark from USA

Will this accept an MP-40 magazine?

asked Leslie from USA


Mark from USA

Can extra mags be purchased for this gun

asked Steve from USA

There are no extra magazines currently available. There should be some available in the near future.

Mark from USA

Why not 52 rd? Like mp40?

asked Scott

Is the magazine interchangeable with the Umarex Legends MP’s magazine?

asked KBF

If the "faux" plastic stocks are not done well this will go over like a lead balloon. I'd pay extra to get wood stocks! Somebody let me know how these faux stocks look and feel!
