The very first GBB Thompson of its kind, the WE model has a full metal upper and lower receiver, with a very convincing wood effect finish on the stock, grip and fore-end. There is some wobble between the upper and lower receiver but otherwise the finish and quality is very good.
It fires from an open bolt system, which means when you charge the bolt back with a magazine inserted, the bolt will stay back. When the gun is fired, the bolt will cycle and continuously fire from an open bolt, just like the real rifle.
Essentially everything on this rifle is made from metal, including the upper and lower receivers, the fire selector, safety selector, front and rear sights, trigger, trigger guard and sling loops.
The metal barrel and receivers are coated with a super matt finish, with laser engraved Thompson markings on the side of the upper receiver.
The fore-end, stock and pistol grip are all high quality plastic with a very convincing wood effect finish.
The included magazine adds considerable weight to the Thompson and holds 50rds.
Adjustable hop-up system is located inside the breach and is a rotary-style system.
