CMMG 5.7mm Banshee upper with a Franklin Armory trigger Take 3 (GOPR0473)

Testing the 5 inch barrel CMMG 5.7mm Banshee upper with a Franklin Armory trigger. NOTE: I fired about 60 rounds with this lower & a lower with standard trigger and had no issues. On the fail video (take 2): upon taking the upper apart I found their was a spring around the BOLT & firing pin. This SPRING was preventing the firing pin from hitting the primer on the round. I rotated the spring on the bolt while pushing on the firing pin and found a position where there was less resistance. I reassembled the BCG and it worked no problem. My issue is with rapid fire I assume the spring will turn & cause interference and thus will NOT fire.
Also see take 2 (where it didn’t work).
PS: Huge thank you to Kimberly L. for the “range” invite & taking the video.
