We have discovered the 7510X can work perfectly with threaded barrels. A simple angle cut using the compound feed on a lathe will allow a threaded barrel to very easily completely drop in with no additional fitting. CGW can cut the barrel for $50.00 plus $7.00 return USPS. So now you can have tack driver accuracy for a very reasonable cost. Example: bushing $60.00, CGW install $30.00, CGW machining of the barrel $50.00, return USPS $7.00 = $147.00.
A very good local machine shop should be able to do this as well.
