Thats what it really looks like. Cost is a little under $3,000, US. It uses compressed air. Scuba tank is about $300 more, plus adapters, about $110. Add a pellet stop $100 and some good pellets $10 and you are ready to go. It gets almost 200 rounds per charge of air. I measured the velocity and its 600 feet per second with a std dev of 5, from start to finish. Other pellets vary the velocity, but are consistent withing their weight group. That little tank on the gun is charged with 200 bar, ie 3,000psi.
Everything is adjustable.
A really fine pellet gun. Note: Yes pellets taste good, I will send you some to chew on, may help you think better.
