got gifted a cmmg ps90 barrel for my birthday, did the bullet test and found that the gunner bullets get a little stuck when put in the chamber. i cant tell what part of the bullet is getting stuck when i stick most rounds in they have wiggle room until i put some pressure on them and then they stick, i took channel locks and turned the bullet and pulled it out it almost looks like there’s a portion of the barrel that is leaving a ring around the bullet when i spin it. the bullet itself not the casing. i contacted cmmg and was recommended to hone out the chamber with a 556 hone. was not given the option to send it in and was not told that it would be covered if i mess it up. i told them i didn’t have a chamber hone and have never done it before and then was given the option to send it in and was told it could possibly take 12 weeks to get back to me. it seems like they’re trying to deter me from sending it in. any recommendations for what i should do?

just curious what else i would need to purchase to build my own 300 bo fde 15 p tired of waiting for them to release more.

finally submitted my form 1 for my ps90 as a individual. any idea on the recent wait times? it’s my first nfa anything so id imagine it’ll take longer than somebody who already has nfa items.
