I'm a gun tech here in the Peg, and I'm having this exact same issue with a clients ICS. However I out of curiosity sake tried it out without the upper on at all. The gears themselves seem to have this timing issue without haviing to pull back the piston and sping.
The gears that are in it are Prometheus from what I can tell. I was wondering if there are compatibility issues with gear sets? Could it be that the Cam on the ICS sector gear is at a different placement than on other gearsets?
I have honestly never had a gun where I have had soo much confusion. I have taken it apart alot, I left play with the gears in terms of shimming and this issue persists.
I can see that the Cut off lever is engaging at what appears to be an off timing. Will complete a full cycle, then a part cycle...etc; just for clarification its also doing this with the upper half connected.
Any Ideas?
