[QUOTE="mouthpiece, post: 3953105, member: 1685"] I did not read the whole thread. I have several of these in 7.62x39 and they run flawlessly but you need to know what to look for to get them to run reliably. 1, First thing is you need to slow down the extraction. use the heaviest buffer that will run with your ammo Or you will continue to break extractors. You have to allow the gas pressure to drop before trying to yank the case out of the chamber. 2, 2nd thing that may help is to regulate or restrict gas at the gasblock If the heavier buffer doesn't help. Are you using a FA(full auto) carrier? It is a bit heavier than a semi carrier and helps slow down extraction. can you hand cycle ammo with/by the charge handle? If so, it is possibly just too much chamber pressure before unlocking. [/QUOTE]
