Anyone here use one of these for rifling inspections? If so, which one do you have or wish you had and why? Looking to get one with a <5.56mm camera for an android phone or one with it's own screen.

PK90,

I've had a standalone Snap-On borescope for a long time.  It came with a small tip, a large tip, and 90-degree adapters for looking sideways instead of straight ahead.  It records video or photos onto an SD-card.  I think there's been lots of progress in the tech since I bought that and there are now some pretty fancy USB borescopes available.  Prices vary all over the board.

Thanks. Yeah, from $20 to $2,000. 

There are a host of them on amazon for ~$35 you have a choice of a probably good enough camera but it's 8.5mm or potato image quality at 6mm. 

Once you get to a decent size, they are wired and come with a display and cost of entry is around ~$130 jsut hit up amazon and search for 4mm borscope. 

 

 

 

 

Got one coming in for $50. Quality and reviews are great.
