Pinning down bolt stick, I think...

I have a 68mag that that is wanting to cycle, (or at least reproduce some type of bolt movement), on the release of the trigger. The marker is mechanically, from what my limited knowledge can surmise, stock other than an ANS bolt.

It did have a shim in the power tube which I switched out for an older style spring due to it being free and thinking it an instant fix. I still have the same problem. it doesn't do it all the time and seems to be more prevalent when I apply certain pressures to the trigger.

I bought a ring kit since it needs an on off ring replaced, but could the power tube ring be what what's casing this?

This marker hasn't worked since I obtained it, for reference.

if i were you i would pick up a new bolt. those ans bolts have caused some people large headaches. ans did not hold the same tolerances when making parts that agd did. also make sure your spring is extending past the tip of the bolt. i would change the powertube oring and see if that helps.

Don't take anything for granted then. Check the on/off pin first and make sure it is .750 long. A short pin is usually the cause of shooting on trigger release. Make sure there is nothing like tape or paint between the rail and the body and valve. Check that the sear pin looks stock and not some skinny piece of nail.

While you're at it, check that you have a rail bushing in there. It's the sleeve that goes between the frame and the rail in the hole for the field strip screw.

Make sure the bolts holding the frame / rail / body together are hand tight and not over tight or loose.

Check the barrel to see if it is hard to take the barrel off. If the twist lock pin is extended to far it will push the body out of alignment.

You can also feel this by holding the body against the rail and squeezing each end to see if the body rocks up and down or not.
