There are barreled actions available. If you want to build or modify a MN, why not start there? Matching numbers do not mean anything on a Bubba Nagant. From everything I've heard, The arc Angel doesn't really reduce recoil any way, and if they fit like the ATI Monte Carlo They aren't worth the trouble. Speaking from experience, if you want to build a Mosin to have a more modern looking rifle that has all the bells and whistles, it will cost twice as much as a new Axis and not near the accuracy. I have one I did that is 100% reversible for $625 but it is only marginally better than its pedigree. It was fun to do but don't expect a cheap way to have a modern rifle.
