I don’t have an integrally suppressed Tac-sol, but I do have a Tac-sol barrel with the shroud, so 11 or so inches are rifled, it is very accurate, with quarter-sized groups with SK match ammo at 50 yards. I also have an integrally suppressed 10/22 with a Liberty Pinnacle barrel, it is a monocore design, which is huge. The rifled portion is only 6” or so. It’s accuracy is okay, but the design of the Tac-sol integrally suppressed barrel looks much better, with a K-baffle design and a much longer rifled portion. I suspect that barrel is very accurate….
