Was out at BOTW today with Breakingcontact and after my first mag which went clean I started having feeding issues. No ejection issues at all, rounds seemed to spit out the normal 10'-15' but either it wasn't stripping a round off the mag at all or it would jam them bullet up into the locking lug area of my barrel marring up the rounds pretty badly. It started out every five rounds or so but once I got to about 5 or 6 mags in it was doing one or the other problem on every shot. Tried eliminating mag problems, tried 4 different Pmags 2 gens 3s and 2 gen 2s and even a GI that BC let me borrow. Went and traded some 556 with one of the guys in the other bays and same problem. I had just switched from an A2 birdcage to a Miculek brake and tried switching back to the birdcage, same problems. Talked to Eric in the shop and he suggested it was either a problem with the gas system (which he wasn't sure of as he says usually you get ejection issues with that as well) or a dirty buffer tube.
Got home and inspected the buffer tube which I've never cleaned but it seemed to have almost no carbon at all just a light film of cold, gunky (but clean) frog lube which should have warmed and slicked up I would think. Then I ran a pipe cleaner with some frog lube through the gas key which didn't seem insanely dirty certainly not blocked up and it dawned on me that I haven't put the obligatory drop of lube in the gas key in at least 500 rounds (gun is around 1200-1300 round count and only ever had problems with a bit of steel I put through it around 1k). Could that lack of lube in my gas key have caused the cycling issues? If not any other ideas as to what could be causing this? As Breakingcontact can attest to, everything else on my bolt was properly lubed up. Could it have been the cold sludgy frog lube in the buffer tube? Would it even warm up enough in there to get it slick, which could explain why it was fine for the first mag while it was still warm from the car but after leaving it on the bench and shooting a few mags out of my pistol and coming back it was cold and sludgy and never warmed up?
Need some ideas here, want to get my trusty DPMS back into the HD rotation instead of relying solely on my 9mm.
