there are about 100 or so AR and AR parts/accessory makes. i'm lost in field. what does anyone know about or have experience with BCM products,esp barreled uppers?
They are a good mil-spec manufacturer. They make excellent BCGs and charging handles, and have a very nice quality upper. One of the better mil-spec companies to deal with. Not who I would use for a precision build, but for a fighting gun they are just fine.
