Lets see...
When the MN was designed the average male was about 5'5" and in the regions it was used in the soldiers usually wore heavy winter coats. The rifle was designed with a LOP to fit smaller soldiers with heavy coats on, not 5'10" men wearing t-shirts. A slip on recoil pad works nicely to get the rifle out and away from your face and take the bite outta shooting it.
As for sticky bolts and horrid triggers, clean the dang thing. More than likely its been sitting in storage, packed with Cosmo, for at least 40 years. No, the trigger isn't gonna wind up as good as most commercial rifles but remember what it is and who it was designed for. If the trigger really bugs ya there are some how to's on line showing you how to clean it up yourself. If you really want, Timney now makes a trigger for them as well.
Accuracy? Well, they aren't usually tack drivers. The bores on most of the rifles are pretty beat up. That said many have been able to get near MOA out of the MN with a little fiddling. Shimming the stock, free floating the barrel, bore polishing, try picking up a couple different brands and manufacturers of ammo (surplus isn't necessarily bad, some users report good accuracy with some) and try shooting for groups with the bayonet folded and extended (many report that their MN's shoot the tightest groups and closest to POA only with the bayonet extended).
The MN isn't a good choice if you want a rifle that you dont have to fiddle with. If you dont mind spending a couple hours tinkering to work the bugs out, its a great rifle.
BTW, im not a MN fanboy. I dont even own one. My personal favorite surplus rifle is the Steyr M95. Its a light and quick handling straight pull bolt action that I love to shoot. I have shot and tinkered with quite a few of the MN's thou and I think they are hard to beat for the money. Sooner or later I will add a couple 44's to the safe.
