AMHsix-
It's pretty simple. The mag is a single stack in the handle. If you look at the pictures, you'll see the square portion with a curved slot above the trigger guard. This is where the hammer is. You cock the hammer using the lever poking out the slot. The hammer faces to the REAR! When you pull the trigger, the hammer strikes the nose of the rocket, forcing the rocket onto a fixed firing pin in the rear of the reciever. This fires the rocket, which flys out the barrel forward and pushes the hammer back down out of it's way, cocking it. Unique, but about as simple as you can get.
The rocket is spin stabilized. There is no rifling, but there are directional exhaust ports in the rear of the rocket. Picture a .45ACP, case and all flying at you. That's about the size of it. As the rocket burns, the exhaust spins the projectile for stabilization.
Accuracy problems would generally stem from the really rotten rocket technology in the 60's (we still blow rockets up today, so you can imagine how good it was back then) or the exhasut fins would get bent and the thing would corckscrew. The fins are just punched aluminum. Figure all the variations in burn rate, etc and it's no wonder they weren't the most accurate things around.
They are VERY light. The feel is almost "toy-like". I've handled several, but never shot one.
