Made by BCM
BCM is an American manufacturer of gun parts, accessories, and all the related things you can extrapolate and imagine from these. It's a brand of Bravo Company, a veteran-owned business started in 2003. This brand represents durable quality for a price that is not prohibitive.
Interestingly, Bravo Company offers nothing that says "restricted to law-enforcement / government use only". Their policy is that law enforcement officials and departments are restricted to the same type of products available to civilians of that same city or state. If the civvies can't get it, they won't sell it to the police, either.
