Feed Cone issues

by likk, Verified Owner from NC, United States Written on May 24, 2025
Only got it to run seamlessly few times. I have gotten more FTF than anything. Will try to sand a polish the Cone of the feed ramp and update. Can not really recommend this upper at the moment. I know it was a cheaper upper so I knew what l was getting into. 3 stars for now
Pros:
  • Price, Finish
Cons:
  • Feed Cone could be better but works.
