Im still waiting on my barrel nut wrench to get my build together. Meanwhile............should I do the extractor upgrade? I do have an adjustable gas block.
BCM extractor upgrade kit. |

Yes, you should. I had consistent failure to eject on my pistol build during my first range session and it was due to a weak extractor spring. It was so frustrating to have a new build that didn't cycle properly. Added the #60 o-ring around the extractor spring as a stop gap and no more FTE.
Don't know if there is such a thing as having an extractor spring which is too strong. This was on a 10.5" with carbine gas. |
