i own one but don't know much. waited 10 months total for the whole thing to close. if one wishes to sell,i assume the paper work and wait is even worse than buying from a dealer. right? talking rimfire here. anyone have any experience with having a barrel threaded for suppressor use? POI changes for sure but what about affect on previous accuracy? i can't help but think that an affect wouldn't be inevitable,especially with a "heavy" barrel. thanks for any info.
