    As a FFL holder and gunsmith, I frequently get work repairing local law enforcement rifles. This auto sear assembly fits properly and functions as it suppose to.

    Do yourself a favor... stop reading these reviews and just order it already, you will not be disappointed! This is the only Colt product I’ll own after they 86’d civilian market sales.
