Used, LE Trade-In RWMD 5.56 Complete Upper Receiver Group. 10.5″ Barrel MLOK Handguard Includes HUX Muzzle Device Radian Ambi Charging Handle Centurion Rail We don’t know much about RWMD but these uppers came from a PD on the east coast. These appear to be 10.5″ barrels. There are no manufacturers markings visible through the rail so on one of the uppers, we disassembled it and took pictures of the markings. We found “RWMD .223w C 7” marked near the barrel extension. It is unclear who the OEM is but it is a .223wylde chamber. These include a RWMD marked BCG that appears to have a Nickel Boron or similar coating. These include a Superlative Arms adjustable gas block
