Removing a Crosman 101 Forearm From the Pump Arm

I’m building a “Frankengun” from parts of two beater Crosman 101 rifles. I needed to remove the forearms from the pump arms so I could swap them.

The two forearms.

One of the pins that holds the thing together.

Cleverly hidden by a plug.

I drilled out the plug with a smaller bit and enlarged.

Transferring the location of the pin to the other side with pencil marks, one hopes.

A smaller drill until I hit the pin and then punch with the pin punch.

When you’re lucky the wood splinters minimally.

It still leaves a ragged hole. It seems as though Crosman slightly peened over the heads when pressing them in as they do tear their way out.

This is what happens when you’re unlucky. In either case I’ll drill the holes a larger diameter to the depth of the pin heads so I can plug them with a matching piece of wood.
