revelation model120 .22

[kalikid]

I have a Revelation model 120 sold by western auto supply co. It ftf every other shot, and the mark on the bullet casing is very shallow. I was thinking the firing pin is worn out(due to dry firing?). I'm wanting to fix this rifle up...new firing pin, and new stock. I've read that this is pretty much a marlin model 60. Is this true? If so, can I just order parts for a model 60?:
