Reassembling the Crosman 707 Rifle, Part 1

Now to get all the bits back together...

The piercing assembly with new o-rings.

This is where the small o-ring goes to seal the piercing pin. 600-85 is screwed into the body to retain the o-ring.

The barrel is slid back into the tube.

Screw 700-31 holds the barrel in place, bushing 700-18 pressed in. I held the new ball (I have a nice collection of bearing balls) on the spring with a dab of grease.

The tap loading parts are reassembled.

The bolt 700-15 is inserted into the tube from the back.

The bolt handle is screwed in. There's a small setscrew inside the bolt handle that locks it in place once screwed in.

The valve is inserted. The screw slots on the end can be used for rotary alignment.

The bolt is cocked, allowing the valve to be inserted into place fully.

The valve in place ready to be attached with screw 700-10.

The band clamp and piercing assembly are replaced.

Just a little more to do...
