^^^ That is me too. A furniture set turns into a rifle.
I think you should keep as many wear parts as you can. Like complete bolt, fire control group, firing pin, springs, etc..
I personally keep a full spring set and a firing pin, and I have crappy Century triggers I replaced with G2s as my backup FCG. I need to get a bolt, but I know you have to headspace bolt to chamber/barrel, and they aren't drop-in parts necessarily, so it's not as easy to get one of those for an AK as it is for an AR.
