Would you guys contact the maker and ask some questions? Shoot it and see what happens?
and yes, I am well aware that borescopes have the effect of making things looks worse than they are with the amount they magnify.
Background: This a custom barrel I just received. I borescoped it out of curiosity, and man, there's some things that worry me. For starters, the coppering seems excessive (yes they test fired it). Though that doesn't necessarily mean a barrel doesn't shoot well. Though based on the cost of the barrel, I was expecting something that was at least hand lapped but likely button rifled. The chamfering on the chamber end looks a bit rough. The crown is a bit suspect. It looks like perhaps the tooling was dull and folded the crown in.
It's an AR15 barrel in 350 legend for reference.
I am no longer using YouTube because they deleted a whole bunch of my videos that were completely innocuous and never even notified me. It was very odd. Went looking for them, and was informed my account had been terminated, but they only deleted some of my videos.
