Love this bcg. Works well with my criterion barrel

Finish looks fine, hopefully holds true to the name behind the bcg

Was wanting a bcm bcg. People simp so hard for hodge, this came in stock and I figured it was a safe bet. The coating is absolutely terrible. It was so bad, I was trying to figure out if it was a counterfeit or something. In a few hundred rounds its already worn to hell.
I have not contacted hodge or bto to make this right yet, but I will, and update this review as things change. I don’t mind wear and tear on firearm items, but the coating of this bcg is trash tier.
