Need Way To REALLY Look At Your Firearm Bore?

I had a pretty neat conversation with Gary from Endosnake. I have been looking for a borescope and this one might be a cheap option that will get me by until maybe I can afford a better one. It seems that they are committed to a good product, as good as it can be AND the fact that it is only 3.9mm means there are not many other cheap options out there anyway, most are 5.5mm and obviously won’t fit in 22 caliber stuff.
