Went to range yesterday to confirm my rifle zero. I observed that intermittently, my safety selector would not switch from FIRE to SAFE during slow bench rest firing. The selector is able to switch again if I pull back on the bolt either slightly (press check) or fully. When chamber is empty, the selector has never jammed whether the BCG is locked back or not. I am running a Daniel Defense DDm4v7pro Lower with Ambi safety selector, POF ultimate bolt carrier group, Geissele Super Dynamic Enhanced Trigger, and OEM buffer and buffer spring. Any thoughts? Thank you in advance for any help.
