At the moment I have a savage replacement barrel coming from Shilen. It's going on My model 11 and I was wondering how big a deal it might be to do the swap Myself. Also was wondering what else should be checked or replaced while the barrel is off, like the recoil lug.?. Luckily I'm not in a rush to get this done so time to learn. Any pointers, first hand stories, words of wisdom and the like welcome.
