I didn't realize they made them for air rifles - oh! You mean to use your regular firearms with it - hmmm - interesting - yes, I am familiar with it; no, I never really thought about using it at home. Hmmm... stuck in my paradigm again... Huh. Still need to shoot, I think - especially with kids - funny how that is. But for serious adult use, yeah, that would be a great supplemental marksmanship maintenance tool - good idea.
