The Black Rain Ordnance receivers sets are gaining popularity on the forum as Brownells has had them in stock pretty regularly which obviously is critical given the current political climate. Black Rain Ordnance also does limited runs of special finishes. The skulls was a hit when available. The two finishes above are the standards. One being Milspec and the other being "Norguard" electroless nickel.
