U.S.A. -(Ammoland.com)- -Some interesting items turned up at the Baltimore gun “buy back”. “Buy back” is an Orwellian propaganda term. You cannot “buy back things you never owned. At the event, someone turned in an expended AT4 trainer. From saab.com:
All AT4 weapons are single shot and fully disposable. You simply aim, fire, destroy the target and discard the empty tube. Furthermore, the AT4 family has proven itself to be a highly reliable, robust and durable weapon system that has been extensively proven in combat. Its key characteristics include high target effect and hit probability – creating a high target kill probability for each fired weapon.
The gold or yellow band on the tube indicate it is a trainer and not an actual AT4. The lack of a cover on the front end shows it has been expended. Used trainer tubes are inert.
They are not illegal to own, because they are inert, and cannot be reloaded. You can buy them over the Internet for $250. The price is that high because airsoft enthusiasts love them.
