I’ve been looking at the Begara B14r barreled actions and am trying to decide between the standard 18.5 inch version and the 20 inch MTU version. I am not the kind of guy who will leave well enough alone so even if I get the 18.5 inch version I’ll be changing stuff a year from now. Just wondering if the extra 400 bucks is gonna save me from rebarreling it a year from now or if I should buy the standard setup and save for a KI later?
