Good basic set by Bill, Verified Owner, August 31, 2017
Everything works fine. Trigger is a little stiff. Next time I think I would pay a little more for the enhanced version from Strike Industries. I think it would be worth it to get the bigger pins. Also no trigger guard so don't forget to order that.
