If I may ask, what is a wrist rocket?
I am allowed (by dear hubby) to have a shotgun, but handguns are off limits. It's for my own good, I know, I am not the most focused person and I think that's probably a requirement. My sister, on the other hand, has all kinds of NRA certificates and is an instructor. :-/
It’s a sling shot with a brace for your forearm. Increases the velocity of the projectile to deadly proportions. You can use .00 buckshot, etc.
