It depends entirely on whose after market parts they are .Something usually like TRW or Bendix is as good as OEM .Then if you get some of that Chinese made chit you get about what you paid for .
I remember a night at a rental cabin with a pellet rifle that ended with 20 odd deceased bats.... talk about effective firearms.
As a rule I thought that was reserved for cats .I figured you would have been slinging lead at it
