      Good Product

      Posted by Anthony on Apr 9th 2025

      I ordered one of these to replace the old auto-sear on my registered colt lower. Great product and highly recommend. I'm gonna order a few more just to have as backups.

      We all know its about impossible for us mere mortals in the 2A community to really use this “ conversation piece”…… That being said, Just a great little piece to bring out of the safe once in a while to start a vibrant discussion… Thanks to Colt for being Colt!!
