This was my first 3D2A print in 300 blackout, I was scared to pull the trigger at the range but when I overcame that fear 60 rounds and only one failure to feed! Went with a PSA 8.5 Upper and CMC trigger. The assembly process was smooth and everything fit exactly as Tim said it would! Now I don’t want to print any other designs because I don’t think they will hold up like his! Thanks again for the great customer service and a functional design and fool proof kit!
