Yes, the WMD Guns M16/AR-15 Full Auto Bolt Carrier Group would be compatible with a binary trigger system.
The WMD Guns M16/AR-15 Full Auto Bolt Carrier Group was not designed to be a left-hand BCG. There are no serrations on the left side for a forward assist. You would also need to purchase a left-hand bolt. I would recommend using a dedicated left-hand BCG.
The WMD Guns M16/AR-15 Full Auto Bolt Carrier Group in FDE (MPN:1-NIBXBCG0005-FDE) would be the closest match to Strike Industries FDE.
