Where and how do you get parts for a Stevens Model 887 22 rifle?

Answer 1

I too was looking for a firing pin for this model rifle. I got it when I was 14 and now that I'm 40 I managed to find that it was in storage at my grandmother's house but, it was missing the firing pin. :(

Upon searching I came across this website and found that the parts are interchangeable with the model 187. So, you can find the parts that you need here along with a schematic of the rifle.

I hope this helps you.
