Well, as the saying goes " you don't know what you don't know". This thing is impressive!!!! I can see cleaning sessions going on for days.... Only kidding...but WOW. For the price, I am going to buy another one and have the mirror set for a larger bore. I can see things being sold out on and off for months to come. If anyone is reading this forum, and on the fence about buying one, do it! I can't wait til I have the time to go thru the bores of my different firearms and observe the bores , leads, and rifling so that I know what's what.Again, thanks to the op for bringing this to our attention, and the members who have posted pics and video about this great item....rsbhunter
