The MN's are fun, after you get past the hard-working bolt and pain in the neck safety. I have a Model 38 carbine that is a right handy little rifle and is a hoot to shoot. I kept it full military except to remove the rear sight and replace it with a short rail (see Darrell's Scout mount here: http://parallaxscurioandrelicfirearmsfo ... iew/id/116" onclick="window.open(this.href);return false;). The Darrell's is an excellent rail and you don't have to modify the rifle in any way - its easily returned to its full military configuration if you want.
I topped that off with an inexpensive red dot sight and it has become a good hog rifle. Its really quite accurate too. My barrel was counter-bored, but it will hold 2" at 100 yards off the rest - definitely minute-of-hog
My accuracy was mediocre with surplus ammo but I was able to dial it in with handloads.
