UPDATE, fixed the problem
So after lots of searching I found a couple people who had the exact same problem I had.
Ironically the best thread with the most info I found was from a year old Calguns posting.
My problem was exactly like the one in this link.
Everything was installed corretly, and to troubleshoot I had swapped out multiple pins and componets and could not really figure out what was the actual cause. I was starting to think the sear angles had slowly wore a little and rounded which may be true, but what was the main cause was the triggers disconnector channel was not quite deep enough after measuring and comparing to 2 known good triggers.
So the disco was releasing to early, before the trigger was lined up correctly with the hammer sear.
Armorers have a name for this, disconnector timing. And they usually remedy it by swapping different componets till one works.
But you can also adjust the timing your self my filing a little bit of material off the front bottom nose of the disonnector, the part that rests on the trigger.
Once you file a small amount install and check your reset again. You could eventually go to far and start having it release to late causing to much travel or worse not reseting.
Its a pretty easy fix if anyone ever has this problem. Just do some searching up on Timing of AR Disconnetor, you will find lots of info.

My original post-
Would it make any sense that replacing a original hammer pin with a KNS Solid hammer pin could cause reset problems?
Particularly the gun firing on trigger reset.
This gun has fired hundreds of rounds with no problems at all. Recently I replaced all my different ARs hammer pins with KNS solid pins after having a factory pin break on my .22lr Upper
And now it is occasionally firing on the reset. The pin fits good, I can't see how it would affect it but I do remember hearing something about Out of spec pins causing that problem.
Any advice would be greatly appreciated. I have the trigger group apart and cannot see anything wrong.
