Not wanting to speak for CCM ... But the dynamics of having spring COIL BIND as a means of controlling travel is damn hard on the spring and would very quicky effect its "Spring Rate" causing velocity issues from reduced spring energy.
** Case in point why AGD used FLAT wire springs on there bolts. Coils never get squished into an overlap situation screwing them up.

* A better solution would be a spring guide (Rod) within the hammer spring chamber that bottomed out into the back of hammer & against VA once a certain stroke distance was made.

One made of delrin would seem feasible.

This is a good idea motor head. I am thinking the easiest and most adjustable way is tapping the front rod and putting an Alllen screw in the tip.

Ok problem solved.When we run bodies again we will put a small cut at a
45* angle or so to the inside so the metal will not mushroom.Kind of like putting a modified countersink or relief cut on the inside.Then you can pump the crap out of it without any mushrooming.

I dropped a length of delrin rod into the bottom pump guide hole to prevent double feeding. This will prevent the pump stroke from bottoming out on the back of the body's sear channel.

This picture demonstrates the fix and the problem I was having. This will address TF's problem too.

Yup. This would do the same thing as my tapped hole and bolt would.

Yours may prevent damage to the pump handle and be replaceable.
