NEW 2020 Stock Just In!

THE classic WW2 US sub-machine gun - loved by re-enactors & airsofters alike!

Full metal upper including outer barrel with ABS lower receiver, and faux woodwork. Comes with a hi-capacity magazine.

FoC battery and charger included!

Note: We do recommend you purchase a better battery and charger as we offer no warranty on the free ones at all.

The military version of the venerable Thompson we all know and love. Modified during wartime production to be cheaper and more reliable than the 'Tommy gun' the barrel cooling fins and adjustable sights were lost and the drum mags were dropped and the mag replaced with a 30rd stick.

Used by the early British commando units, the drum mag was quickly found to be too heavy & too noisy, being replaced with 20 or 30 round box mags. In US Service, it was taken up by the USMC well before WWII, but was supplanted by the M1A1 version very quickly. The 1928 was found worldwide for many years after WWII however, used amongst others by Israeli terrorists in their efforts to drive the British out of Post-War Palestine, a testament to the gun's longevity & reliability. The example tested was shooting at 375 fps with 0.2g BBs, so check you site limits! We do not guarantee that all of them will shoot at this velocity as spring consistency is almost non-existent in China. Yours may shoot bricks out of the side of your house or it may tickle the lovespuds of your resident tree squirrel, who knows?

CYMA CM033 / CM.033 M1A1 Thompson Sub-Machine Gun AEG Airsoft Rifle
A great historical and Iconic SMG
Review by
The Thompson SMG is an iconic weapon and deserves a great AEG airsoft version. This Cyma M1A1 Thompson really does not disappoint.

The majority of the black components on this gun are metal (yes a metal receiver for well under £150). The lower receiver is plastic but you honestly will not notice this. The 'wood' is also plastic, but is very well done and looks convincing, and I suspect if this came with real wood furniture it would probably double the cost of the gun. You could always add a wood kit to this if you wanted to, but it will add a lot of extra weight. The metal has a nice black finish to it which looks convincing and seems reasonably durable. There are no markings at all on this gun, but it does look and feel great.
This comes with a Hi cap wind up mag which works great, however I don't like the way wind up mags rattle as they get empty, and so I bought 3 low cap spring mags with this. These spring mags at Tokyo Marui ones and work perfectly in this Cyma gun.
The included battery is ok, but rate of fire is a bit low. A higher voltage NiMh or a LiPo would probably sort this out, and the battery compartment is a great size to handle whatever power source you choose. There is no MOSFET fitted to this gun, but it should be relatively easy to fit one if you wanted too.
My gun shoots nice and straight out of the box and the hop up handles the .25g BBs I like to use with no issues. Range is reasonable.

Overall this is a great AEG, that looks and handles just like a real M1A1 Thompson. At the AirsoftWorld price this is a real bargain too so if you think you might like it just go for it. Its a lot of iconic full auto fun for the money.
