One of the more interesting things on display at the FNH booth was this air powered training system. Using a target on a far wall and a little black box on top of the gun, the computer can track how your gun moves as you’re aiming and records where your shots would land. It also uses a gas powered system to cycle the bolt and simulate recoil on the gun. The full kit runs about $5k, but the slimmed down civvie version can be had for $1.5k. It seems like something that would be really useful for firearms instructors. And I might want one for dry fire practice as well.
