The MantisX Blackbeard AR-15 Personal Firearms Training System is the perfect product for you if 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 and 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 AR trigger reset machine. Installation takes less than a minute. Break open your AR, remove the bolt carrier group, drop in Blackbeard, close your baby up, and put the magazine in place to provide the power. It's a 20 second change-out. Dry fire away, counting how much money you're saving with every sweet trigger break and reset that you hear.
