Thanks! I will tell you that I learned a hard lesson in barrel finishing. Finishing a slimline is really easy with a pen mill, but with a 10.5mm(I think), getting the tube perfectly square is difficult. I did find that if you take a look at the Library and pull up the spreadsheet for bushing and tube diameters for all the different pens, Penn State Industries will probably have barrel trimming sleeves for their kits that you can use on anything else the same size. I believe that their Majestic barrel slimming sleeves comes with not only a 10.5mm but also a 12mm sleeve!! And only for $5!! You won't be able to clean out the tube, but for squaring, it seems worth it to me. Just a heads up for you guys. I just hope I'm letting someone's cat out of the bag!
