>>8769278I only have the one.
Seriously though, I've never had issues when I was using green tip for 4 years. However, in the civilian market you get shitty ammo, and in a situation where you can't afford to be picky about your ammo your shit will get fucked up. I speak of wolf ammo, as that is my experience, I managed to get through about 2 mags before I was getting jams on every shot. I switched out mags to no avail, even gave the bolt a light scrubbing.... nothing.
I took the bitch home, soaked anything metal in hoppes, scrubbed the living shit out of it and spent a good portion of my life cleaning out the gas tube with fucking pipe cleaners. Took it back to the range and it burned through another 2 mags before jamming non-stop.
Repeat cleaning process, this time I used black hills. No jamming problems...
