We get a lot of request for DROP-IN replacement barrel and even though we do not make them there is a man in Knox, Pa that get barrels from us and does just that. I have received emails back from many customers thanking me for send them to him, he does very nice work. He orders the barrels from us then finishes them out for you. His name is Dee and you can contact him at mountintax@aol.com . Many customers are interested in converting their T/C, Lyman and etc to a TURKEY CHOKE barrel. This requires a barrel of 1″ across the flats min, along with 58 and 62 rifled. in 15/16 across the flat barrels we can do any caliber up to 54 rifled and smooth bore to 24 ga (58). So if you are looking for a drop-in, please contact Dee at the email above.
Thanks, Scott Keller Colerain Barrel Co.
