I haven't had any experience with the Clerke brand except over 20 years ago there was an outfit by that name that made little junk revolvers out of pot metal. I doubt it's the same company. If I had a question about a 10/22 barrel or other aftermarket part I would contact CPC at http://www.ct-precision.com. George
