WMD guns AR-15 FC

I have not used that brand, but I have used Spikes "Battle Trigger?", which is Niclel Boron coated. My belief is that with the lighter springs it is a decent trigger. It actually is pretty much what one woujdl expect, still a GI, but smoother out of the box than any GI I have used. Also, there may be some benifit to the coating in terms of resistance to corrosion, if for example, it was being used as truck gun?
