Did some shooting today. Gun is well lubed, even the sled.
With two different Lancer mags, failure to feed. Even using the bolt release on a new mag, the bolt would not pick up the 1st rd. Bolt always locks back after last rd shot.
With Pmag Gen3-- Didn’t have (out of only 10rds–limited ammo) any failure to feed, but the bolt would not lock back after last rd. I only had 20 rds with me today. Ordered more. Same PMC X-TAC. 62 gr.
Brass ejecting around 3:30 w Pmag. Around 3:00 with Lancer. Gas block wide open. I think there are two issues going on. One, the gas block is crap causing weak ejection with the Pmag and the other a possible manufacturing defect somewhere creating the feed problem with Lancer mags. No AR should have problems with new Lancer mags. Opinions?
