Pretty neat piece of kit.

I bought a 12.5" Wolf A1 upper, and was having trouble sighting it. Come to find out, it was shooting groups at 50 yards that were bigger than than the target. I've never experienced this. I've had guns that failed to stabilize bullets shoot more accurately at 50 yards. This was a new upper and currently has a couple hundred rounds through it. Video recorded with a Teslong borescope.

New custom barrel that I am evaluating. Initial bore-scoping didn't look too promising with the crown and bore looking a little suspect. Chambering and throating looked pretty good though. This is after firing 30 round or so. Accuracy isn't looking promising either. I am wondering if the termination of the copper following short of the crown is indicative of an issue.
