Rock River National Match Trigger Problem

[klassik]

I just bought a RRA Entry Tactical Carbine about 2 months ago. I have put about 1000 rounds through it and the NAtional Match trigger went from an awesome two stage setup to a single stage with an exteremely long pull. The pull is sooo loong and there is no way to tell exactly when the hammer will drop. Has anyone else had this problem? I am sending the lower back to Rock River so they will fix it. I just need to know if this is something to expect from this sort of trigger with hard use. I didn't see any reason for the malfunction like pierced primers and I take care of my AR. Maybe it was just a fluke, If it wasn't though I already have a brand new mil-spec trigger setup I ordered from RRA just in case. It cost like 40 bucks with shipping but it's nice to know that it is there if I need it. But when that trigger worked, man what a trigger, beautiful.
