Helpful Positive Review
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.

Great BCG for the price by Wayne Mirka, Verified Owner, August 13, 2020
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.
