Actually I believe he is. I pm'd him directly earlier and he's indicated he'll do some measuring so a big thanks there. This is a more general enquiry. I believe Chops does a lot of conversion work in knocking down SL8 barrels to C version length. This is more of an enquiry as to what the actual dimensions are as the plan is to attempt to make one ground up from a blank. I want to keep the original as is.I think chopstix kid would be able to help you.
