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!

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.

I used Crosman Copperhead BBs and Powerlet C02 and these seemed to function well in the Thompson. This thing is just too much fun! It might be a little noisy so your mileage may vary with the ability to firing it in the backyard without scaring the neighbors.

The M1A1 Thompson Umarex is just plain awesome. It will rip through a magazine in less than 2 seconds or so it seems. The stock looks surprisingly very much like wood. An original style Kerr M1A1 sling fits just fine. Once the magazine is empty, the firing ends, so no wasted CO2 blowback action.

It would be nice to have a wood option. Magazines are fairly pricey but then they are not just a simple spring and metal housing deal but also contain the energy system with space for two C02 12g cartridges. The biggest drawback was the shipping delay both from the depot (understandable with the demand and the strain put on companies having to comply with closure orders) and the delivery company which teased me by saying it was being delivered on Saturday and when 9PM came and went, it only said "pending". But lo and behold it arrived sometime before noon on Monday. Couldn't wait for the workday to be complete. Went out to the backyard and fired off 4 clips. The CO2 cartridges are great for two mags worth. Pretty good on the third and just wasting BBs on the forth. So practically, you should just use it twice and replace the CO2. Though even after 4 uses there was still pretty good pressure to be releived when undoing the plug.

Feeds Dust Devil BB's just fine - using a .22 bullet trap in my garage since it's been raining (oh, and the COVID thing) with no ricochets. Great boredom reliever! Even on full auto - easy to control and very accurate at 20 feet (about as far as I can get in the garage).

Amazing rate of fire on full auto, realistic weight and even the faux wood furniture looks very real. Lots of fun, rips through a 30-round mag in 2 seconds with very impressive velocity.

The shoulder stock is hollow, and is obvious when the sling swivel hits it or you tap it. I removed the butt plate and stuffed a few old socks I don't wear anymore into it. Deadens the noise, so it is less obvious and the fix is reversible. Even close up, it's hard to tell the stock isn't wood.

I have a Drozd Blackbird with chip and hpa with fps's over 1000 and if I had to pick only one it would be the Legend M1A1 hands down.

So far I like everything about this gun. Full auto dumps the mag in 2 seconds, outstanding rate of fire. With fresh C02 this beast will easily take care of problem rodents. Accuracy actually amazed me even on full auto.

I really can't find anything to complain about, it's that good for the money.

I received my M1A1 two days ago, but I’m supposed to be sheltered in place, (COVID19) so I haven’t had a chance to take this beauty for a ride. And it is definitely a beauty, very faithful to the original. I have 1 suggestion, a drum mag, even if it only held the original 30 rounds - if only for the aesthetics. I would definitely buy one, and I don’t doubt that many others would join me.

One very minor issue. The sound of the sling swivels hitting the hollow plastic stock. The “wood” stock looks good, but it doesn’t sound good. If I put a sling on it, it would probably muffle the sound.

Umarex did it again....this M1A1 will not disappoint!

Just completed my first time firing and I can sum up the experience with one word...WOW!!!!! Accurate weight and feel even the Simulated wood stock. Great fun plinking single shot from the shoulder,but zipping off a burst in full auto from the shoulder or hip....well, if that doesn't put a SEG on you face, nuttin' will.

An adjustable rear sight might be nice but the fixed one works just fine An earlier reviewer mentioned the sling. That might be nice but the swivels are already there and authentic Kerr slings are readily available and cheap, so again not an issue

If Umarex could throw in a matching/correct rifle sling, that would be really nice.

Awesome design, fun to shoot. A must have if you are an air rifle enthusiast.
