The FNC is an amazing gun. Yes parts can be difficult to find, but out of the 6 semis and 4 machine guns I own, the only part that ever broke was a firing pin and that only happened one time. I replaced it with a titanium one and it keeps going. I have over 30k rounds all together through the full auto ones and went through that one firing pin. I run my guns, but dont beat them up, I shoot them, let them cool, keep clean and lubed. I don’t try to run 10 beta mags back to back. Not saying you won’t break anything but for the money they are great guns.
