read the barrel burn out post. agree that at the price no reason not to have a scope. but,questions. does the teslong work with just a plain simple desk top comp? i have no laptop,cell phone or any other tech stuff. not getting any either. scoping in the home office is easily done. also,is there a tutorial or guide included to teach one what you are looking at? never looked thru a borescope before so don't really know what i would be seeing without guidance. great thing for evaluating cleaning practices and barrel wear. tx for replies.
