I recently had a OOB discharge a couple weeks ago and since I replaced the extractor almost every other shell is a misfire. Not striking the case at all. I've checked to be sure the bolt is closed completely on each shot and that's fine. I got around 3000 rounds through it and other than some crappy ammo in the past I haven't had any problems at all. I did disassemble the bolt to check and be sure it wasn't damaged and it was bent or look broken. I am using an extractor from taticool i think it is. It looks completely different than the original and not sure if it's in properly. The flat tab on the end isn't centered, it's closer to one side than the other. When it's in one way the extractor will move back to the outside edge of the bolt and when I flip it it only moves back to just past the edge of the casing. Any ideas?
