Unsafe or defective… - Geissele Single-Stage Precision M4 Curved Bow Trigger

For $246 one would expect this trigger to be everything needed. Not the case. Maybe I received a defective trigger. The one I received sits with a tilt or angle towards the trigger hole which makes the lbs in the pull next to nothing. I’ve tried different springs with the same tilted angled effect and pull. The bolt carrier group closing caused my AR to slam fire. Not once but twice. Good thing my muzzle was down range. I would not recommend this trigger to anyone! This thing is dangerous. Again maybe I got a defective trigger but for the price you expect it to work how the description states.
