In the series of spare parts needs I wanted to add our beloved AK rifles. This one is very simple because it's a simple rifle.
#1 Recoil spring (if the gun has one then it gets lots of use and is automaticly on our list)
#2 Trigger kit. Tapco has a very nice trigger parts kit but it doesn't include springs. A hammer and disconnector spring will top this list off. A spring kit is available at K-Var.com. It includes 1 Recoil Spring, 1 hammer trigger Spring, 1 Mag catch spring, 1 extractor spring, 1 Disconnector Spring, 1 plunger pin spring, and 1 pivot pins retainer spring.
#3 If anything else wears out any time soon you are abusing the weapon.
I did say it would be simple. Next is the H&K series of rifles...not so simple.
