Briley is NOT currently sleeving barrels. There was a big shakedown there about 6 months ago and the gunsmith who physically does the work got let go. I actually had a gun there in the due for sleeving that got returned to me untouched due to that whole mess.
Merrington is the only person that I have personally had do work for me that I know of doing the work. I would like to know some others.
The other issues with this whole sleeving thing is not only who CAN do the work well, but also if they can get tubes. That is a big problem for Kirk right now.
