Trigger was very tight. - Black Rain Ordnance AR15 Lower Parts Kit with Drop-In Trigger

Everything went together very smoothly until it was time to drop the trigger in. What I thought would be a “plug and play” tigger gave me quite a bit of trouble. I’m not sure if it was the finish on the trigger or on the inside of the lower but it took a bit of force and some light sanding on the corners of the trigger group to fit correctly. After I got it in I am quite pleased with it. Hopefully it was just a fluke and the next person has better luck. It went into a Aero Precision lower.
