A few weeks ago someone was asking questions concerning the availability of Green Mountain .40 cal. barrels. I talked to Tip Curtis today concerning some parts, and also asked if he had any .40 cal G.M. barrels in stock. He said that he had .40 cal. barrels available now from 3/4 up to 15/16 across the flats. His number is 615-654-4445. He has been visiting his family in Texas and has not been home for a bit, so you may not have been able to get in contact with him earlier. Hope this will help.
