Just wondering what size jets guys are using with a 10” barrel on the 16. I ran a 1.85 for about 2k rounds of wolf steel case, 1000 or so of which was suppressed. The gun started failing to lock back and was not picking up succeeding rounds after this point. Cleaned the piston for the first time and thourouhly cleaned the carrier, bolt, and receiver, and installed a 1.8 jet. It’ll run that one now. Not sure how long it’ll run, but I think I’ll try it for a while. FYI, my research has shown the factory cqc size is apparently 2.0.
