I'm leaning towards the pring being too heavy. In the past when I've used Prometheus springs, I found them to be about 10% under-rated. For example, the MS110 gave a velocity of 400 fps, MS100 was 365 fps, MS90 was 330 fps, etc. I would expect the MS120 to be about 430 fps. With a standard ratio gear set, That's a tough load, and my ICS M4 used to lock up when I had the MS110 in it, even with a big battery.

The "SP" designation you used is Guarder, not Prometheus.
