Thompson AEG Air Nozzles
The Thompson (M1A1) AEG is a classic-era gun that uses a platform-specific nozzle. Because these are often older or clone designs, buy a nozzle listed for the Thompson and confirm the length by measuring the stock part rather than assuming a modern M4 figure.

How AEG nozzle fitment works
- AEG air nozzles fit by length, and length is platform-specific: An AEG air nozzle is not universal. It fits your gun by its length in millimetres, and that length is set by your platform: an M4 runs about 21.4mm, an AK about 19.6mm, a G36 about 24.5mm, and long-receiver guns like the SCAR-H run much longer. The internal fit to the cylinder head is broadly shared across standard AEG gearboxes, so the number that actually decides fitment is the length. The reliable method is to measure the nozzle you are replacing and match that, then feed-test.
Fitment notes & exceptions
- Measure your stock nozzle: The Thompson uses a platform-specific nozzle and these are frequently older or clone designs, so measure the nozzle you are replacing and match it rather than assuming an M4 length.
