Yes, it is to original length, you can just see the vertical line of the patch in the second photo. It came out pretty tight though. I didn't want much of a glue line.
I imagine I'm going to be doing more of these, I've got one to do for myself, and I'm working on doing .223 conversions of No4's and No5's for range use. There is much to be detailed as yet, but the fundamental components and requirements of the project are together. I hope to have a running example, and a template for "production" by the end of September. My guess is many will want these in No5 guise. Sharpen that spokeshave!!
