Phase 5 Weapon Systems Inc AR15 Bolt Carrier Group (BCG), Nickel Boron Coating BCG-AR15 NiBX
I have had this BCG for 6 years and it runs flawlessly with ZERO issues. It cleans up well with just a rag. I have only used it in 556/223 but I'm sure it run would other calibers just fine with the proper bolt.
I was looking for a mil spec bcg that was nickel boron coated and found this one for a great price. The coating really helps keeping it clean. I am running it in two of my builds and haven’t had an issue with them yet. Exactly what I was looking for.
