Description

Famous for its time in military use, and infamous for its use by gangsters during the prohibition era, the M1A1 has a storied history in the United States. Commonly referred to as a "Tommy gun" and "Chicago Typewriter", the real steel version saw U.S. Military service from 1938-1971.  The .177 caliber steel BB version features the same iconic looks and functionality as the firearm.  

A 30 round stick magazine houses two 12 gram CO2 cartridges that provide enough power to sling steel BBs at up to 435 fps, as well as give an enjoyable recoil impulse thanks to the blowback action. The rifle can be operated in semi-auto or full-auto, sending a full magazine of BBs downrange in a matter of a few seconds.  

Well known for producing some of the most enjoyable replica airguns on the market, Umarex brings yet another historically significant firearm to life in airgun form! Era correct faux wood furniture, sights, and sling mounts make the M1A1 a replica that even the most avid collectors will be impressed by!

Accuracy/fire rate/looks/feel

The last round/bolt hold-open.

What an amazing bb blaster. The fire rate on the Thompson is ridiculously fast/awesome! I'm able to hit dead center on beer cans at close to medium range and it hits surprisingly close to p.o.a. without adjustable sights. I have put thousands upon thousands of bbs through mine, and the only malfunction has been the bolt stop lever's resting point on the slide. The slide is soft pot metal and I wish there was a reinforced steel piece where the lever rested upon firing the last round. For as much fun as this crazy plinker has brought me, I'm not going to sweat it. I removed the lever and I just keep count of my shots/bursts as to not wase co2 on dry firing. Absolutely love it 3 years later.

Douglas Nov 29, 2024

I also have noticed the issue (the only malfunction has been the bolt stop lever's resting point on the slide) that is the sear lever and when the mag is empty the spring in the magazine pushes the sear down to stop the bolt from firing. All that is requited is to slightly bend the sear back to straight (right angle) and file the bolt so that it catches the sear instead sliding inwards off the bolt. It is an very easy fix. I have shot about thousands of BBs thru my M1A1 this is the only issue I have ever had with my Umarex M1A1. I also converted wood furniture to my M1A1 Umarex and it is my favorite Legend's BB gun.

LOTS OF FUN!! The full auto switch is the FUN switch! Very realistic looks and action. Even the plastic stock is almost as nice as real wood. You can't tell the stock is plastic until you tap on it. I think the stock is a better rendition than the stock on the Ledgends Cowboy Rifle. The M1A1 is much more accurate than I was expecting. The trigger is a little stiff but if you shoot full auto, I don't think it matters. I found a replica sling and magazine pouch on ebay and these items compliment the rifle and make it even more like WW2 weapon.

I thought I wanted a wood stock but I am perfectly happy with the stock it came with, so nothing.

If you use Crosman CO2 cartridges, you might need a spacer between them so both are pireced. I use a penny. Sometimes I put one full CO2 cartridge in and one empty one for shorter shooting sessions. Stock up on CO2 and BBs you go through them fast.

I own multiple automatic bb guns.crosman, umarex. This is my favorite.

Added aged leather strap. Drum magazine option would be fun.

Get ready for a good time.

Charlie Dec 01, 2023

In February of 1942, the US military accepted the redesigned Thompson that included changes to the Bliss block locking, and moving the charging handle to the side. That would seem to mean there were plenty of top charging handles in the military inventory prior to '42, and would remain in service until they came back to the armorer who may or may not have removed them from service.

i bought one of them. really nice. with 1 exception. the one exception used in WW2 model to charge the weapon it had a bolt pull back on top not on the side.

I really liked the "authentic look and weight".

Th e magazine was a pain to load until I made a little "tool" .

What everyone should know is that this gun is really just a piece of overpriced JUNK by Umarex. Umarex customer reps are very rude and unhelpful. It is my theory that this gun produces so much "torque" on full auto that it will literally bend the inner barrel, (which is just a cheap aluminum tube). The aluminum inner barrel is only supported by the breech seal and a small plastic carrier grommet at the end of the barrel, the rest is just "hanging in the air inside the outer barrel". I am in the process of repairing my Thompson. First, I had to straighten my inner barrel. Then I put rubber support grommets all along the barrel inside the outer barrel, then I filled all of the "open space" with FlexSeal. I haven't finished it yet, but I know that when I fire it on semi or full auto the inner barrel is not going to move or bend. I have been trying for quite a long time to get an inner barrel made out of stainless steel. That would solve a lot of problems. Very inaccurate ! Barrel moveme

Douglas Nov 29, 2024

I purchased my Umarex M1A1 several years ago and have put several thousand BBs thru it, (about 5-6 thousand) and it is my favorite auto BB gun. I never had a barrel issue with the BB gun. I have taken it apart many times (separated the upper and lower) to fix the sear issue '"jamming issue" it still works great. So I am not sure what is going on with your barrel in your gun. I just try to remember it is just a BB gun and not a real firearm made of steel and meant to go into combat.

Bullitbanditthapaintboss@gmail Feb 23, 2023

sounds like Umarex needs invest in fixing the clip Issuses with the clips and the Barrels I was gonna buy one just for the historical reasons of it but have decided not to. because I be pi@#ed off to deal such problems for a over priced BB gun so sorry for Umarex won't get my $$$ for a BB gun that has Design flaws. thanks for you honest review of that awesome pile of JUNK!!!!!!!

Very accurate insofar as details. Beautiful recreation. Fun to shoot

Loading mags is a pain. They should have a stop similar to the ones used on the M1 Carbine.

This gun looks and feels like the real one . It handles well and shoots accurately. Nice piece for my collection All is good !

I have short arms and therefore my reach is not as I would like. Meaning that the shoulder stock is a bit long but I can ask. to that .

It reached my expectations and very
happy with the performance
it could if possible, hold a bit more BBs
LOL
