For those rainy afternoons or when you really do not wish to go out and fire your weapon and then clean it again..... I have found the above product great. Actually some FBI field offices are using this item.
BeamHit has a great poduct and NO I am not a dealer. I have mine hooked up to a computer and it records my timing, shot group, and other items crutial to pistol shooting. Oh, yeah they are coming up with the .223 rod for your ARs also.
I have my chief talked into one for the department. We are going to require weekly training on it and it will only take about three or so minutes per offcier. The system can exagerate different distances for you and can get sillohette targets and such. The only draw back is no felt recoil.
Thought some of you would like it.
