How did you shorten the cocking tube, I need to do this but want to do it without breaking welds and redoing it. Did you use a file or something?
The cocking tube is held in by the cocking handle pin.
A few tools you will need:
Small punch and hammer.
Masking tape to protect finish if you are setting it on a bench. I.just hold it in my lap sitting in a chair.
A way to mesure before and after cutting.
File, grinder or other way to make tube shorter.
1. Figure out the gap you have now. You need to be able to lift cocking handle about 1/2" before the tube contacts the carrier. The gap should be about the with of a dime.
2. Remove stock, grip pack and then cock the cocking handle to remove carrier and slide it out of receiver.
3. With the cocking handle in the down position, slide the handle and tube to the rear before the catch notch. Slowly rotate into the notch and look for the pin. The pin on both c93s I have are removed by using a punch from the right side tapping it out to the left. It also holds the cocking handle spring also.
4. Remove handle and spring. Note how the spring tabs fit into slot on the arm. There is also a slot for the other tab to fit into on the cocking tube "head". You will see it better after removal.
5. Slide out tube from receiver.
6. Note slot for spring tab on cocking tube.
7. Remove material (make shorter) by grinding on the end that pushes on the carrier a little at a time. Keep checking OAL. Also keep face square as possible.
8. You should reassemble and test. A trick to the handle spring is to controll the tube with your fingers threw the ejection port. Slide the tube "head" into the support tube, so you can push the spring tab into the cocking tube slot as you put the handle and spring into the cocking tube. Pin will fiish aligning as you drive it back in left to right. The pin is tapered. Small side first.
9. Go slow and remember "gap of a dime".
10. Assemble and disassemble until it is right.
Good luck.
