Disassembling the Crosman 707 Rifle, Part 2

On to the valves...

You can see the o-ring split when I tried to remove it. A good hint that the o-ring has seen better days.

The cir-clip was removed.

The valve guts.

The valve "stem" 700-39. The seal face looked ok, so I decided to try reusing it. There was no obvious way to remove the steel button, so I would likely have had to drill out the back of the stem and press the button out. If I have to, I will, but if it holds gas then no need.

The piercing assembly.

The roll pin was punched out.

The components.

The o-ring also split when removed.

The tool I made to work on the 38T valve fit the slots in the piercing assembly as well!

Once removed I fished out the small o-ring that seals the piercing pin. It too will be replaced.

The sear. Notice the complex cutouts in the stock. There is no trigger safety on this rifle, instead you can lock the bolt when cocked, against firing.

One of the ugliest stocks ever. Why Crosman went with this plank-like look is beyond me.
