Looking for a good bore scope recommendation

[john keyes]

looking for a good bore scope.  I have been reading about people seeing what looks like a dried lake bed ahead of their rifle's chamer, lands wiped away, throat erosion etc. 

the one that I really remember is Doesniper talking about his 243AI   




what kind of tool do I need to see this kind of stuff? 

are they real expensive?

Go to a place like Academy or other big sporting goods store and look
for a bore scope attachment made for the AAA Mini-Maglite. Cost is
about $7 or $8. It works as good as most and better than some. Browning
also makes a pretty good one.
