Faulty ICS DMR W/Box

Old modded ICS M4 variant rifle

Comes with a few different springs and a MOSFET to switch between full auto and DMR setups.

Gun has a feeding issue when set up as a DMR, causing it to dryfire spontaneously. Never had the issue with lower power springs on full auto, but I didn’t exactly use it much in that setup. Never could figure out the issue, but there’s a few spare parts thrown in there as leftovers from my own attempts to resolve the issue.

Message for any details and I can run you through exactly what’s inside, plus send any vids for those curious.
