I have started to collect full automatic pellet and BB airguns. And of course the SMG 0.22 full automatic pellet gun was high on my list. It resembled the Thompson submachine gun of the 1920's but it lacked much in appearance, see first picture. Even with the supplied stock attached it was not a good looking gun in y opinion, see second picture. It also had the problem that it was difficult to bring up to your shoulder to use the fixed sights. So I decided to make it more similar to the original Thompson. I made and attached a wood stock and wood fore grip that had the Thompson submachine profile, see the third picture. The Large CO2 tank hanging from the frame was replaced by a feed cable so the gas supply tank does not detract from the lines of the gun. Performance of the gun should be greatly improved since the original CO2 tank which gave 900 psi at 75 degrees F was replaced by a high pressure air tank at 1200psi. Haven't tested it yet but will soon.
