Rough sear, terrible break - CMC Triggers AR-15/AR-10 Single Stage Drop-in Competition Trigger

Maybe I just got a bad one. Installed on a new AR-10 build. Very disappointed to feel two, distinct and consistent scrapes before the trigger broke. Must have tried it out ten times, each time hoping it would somehow not do it again. Nope. The drop-in style made it impossible to access the sear, or I would have tried to polish up the contact points, clean it and re-apply some fresh grease or something. This is a major imperfection that makes it impossible for a shooter to enjoy the benefits of a "competition" trigger with a light break. Ended up having to return it. I'll go back to a Timney or some other reliable brand.
