Gunnut4life's Review of Diamondback Firearms OEM Replacement FN Herstal M16 Barrel

This barrel will not allow rounds to feed. They constantly get stuck on the feed ramps. I can get maybe 1 in 5 attempts to actually chamber. I have built between 70 and 100 ar type rifles and have only had this happen 1 other time but i cant remember the brand of that barrel. I could reprofile the feed ramps with a dremel but it is not worth my time for such a low quality barrel. I will be returning this barrel.
Pros:
  • None
Cons:
  • Feed ramps out of spec
Best Used for:
  • Hammer, paper weight
Would Recommend: No
