You want to be able to do dry fire practice with your AR-15 without having to run the charging handle between shots. An auto-resetting trigger sounds like the perfect thing. This is not a drop-in trigger kit that you can swap with your trigger. This is not a modification to your existing trigger. This is a drop-in Bolt Carrier Group + magazine that works with your existing trigger. It has the same weight, break, and reset. Your dry fire practice just became 100x more effective and engaging. Using electromechanical wizardry, Blackbeard allows you to take up to 10 dry fire shots per second, quickly resetting the hammer between each shot. The ultimate Mfg: Mantis Tech Llc
