I bought a used PC Victory with the carbon barrel. It light strikes on the LAST rd of the mag about 90% of the time, whether I load 8, 9, or 10 rds. No light strikes on any other rounds in the mag, just the last round.
Does it with the original 2 mags that came with the gun, also with 2 new mags I bought later.
Took bolt apart and cleaned everything real well. Including firing pin, spring, etc. Still does it.
Any other tips or things I can try?
