Most of the M-14's were eventually had the selectors removed for the same reason as the FAL's. The show never did get into the FALO squad automatic version of the FAL. Most worked fine and were okay but the FN guys never did figure out bang - bang - jam that would happen on some of the guns.
Mosins are like an acquired taste. If you have only seen some of the more worn examples of the gun, you might have dismissed it as rough compared to a Mauser or an Enfield. The Russian versions sights aren't the best but neither are some of the Mausers . Take a look at the rear sight on a Persian and you'll see what I mean. The Finnish Mosins tend to be at the highest of the food chain and for good reason - they fixed what was wrong ( except the bolt handle ) with the base Russian model. 2 of my peasent rifles are Finnish and the M91's sights are way better than the Russian guns. My M39 is the best of the peasent rifles - excellent sights, curved stock tang ( making it stronger ), and generally making the Mosin even more rugged than the originals. I should have grabbed one when they first came out - cost me $184 to correct that problem.
The only real jams that can happen with the Mosins are if you don't put the rims right in the mag. Get it wrong and the gun binds up. Enfields can have the same problems so it isn't just a Mosin problem. The only other problem I have with one is that it likes to loosen the action screws. You do have to make sure that they are tight or you'll have the rounds dropping on the target. Frustrating when you're trying to zero/shoot it and the round impact on the target keeps changing!
I'm not biased - I own 3 Enfields ( 2 Brit, 1 Ishapore 2A ) and 5 Mausers ( RC, YC K98's, Persian, Yugo M48, and a Polish WZ-98A) - I just like the Mosins a bit more.
