Large pin colt geissele 05-123 - Geissele Super Semi-Automatic Large Pin Trigger

I was looking for a replacement upgrade trigger for a Colt 9mm AR large pin that had a factory installed sear block. Most drop in triggers were blocked by the sear blocker and I didn’t want to alter the weapon. Installation was easy if you have experience with AR trigger groups. Range test 100 rounds was flawless. Always been happy with Geissele products.
