Hello everyone. I'm looking for a piston-driven 300 blackout upper with a 16" barrel. I've looked around a bit and am having very little luck. The only ones I can find are the BRN-180 but all are too short. I also found one but they were 1K+. BCA has side charging uppers but I'm not sure if that makes them piston-driven. Any help is appreciated.
