This episode is also brought to you by MantisX
I’ve been a long time Mantis user from their original MantisX to the Mantis X10 and now excited about their most recent product Mantis Blackbeard X.
The Mantis BlackBeard X combines the MantisX10 and the Mantis Blackbeard into one platform for the AR15.  It unleashes a completely new capability with in-depth dynamic shooting analysis.  Including motion-based analysis and multi-target engagement.  Something no one has done before.
Mantis BlackbeardX connects to your smartphone via bluetooth and you can easily download the MantisX application that gives you all the drills and history from previous sessions.
MantisX changed the way I train and I think you’ll find the Mantis BlackbeardX it a great training aid for yourself and your students.
Checkout MantisX.com for more information on the Mantis products including the new Mantis BlackbeardX systems.

    How’s it going Fridge. My name is Kenny, owner and operator of DJr Empowerment Group, LLC (USCCA firearms instructor) and JettaMan Designs (Pistol and rifle building and custom designs). I caught the podcast on Firearms Trainer Podcast and enjoyed it thoroughly. We need more people like yourself with the each one teach one mindset. I came from that same camp. I’d been teaching for more than 15 years before I made it official and I was building/customizing guns for 2 years before I became a C.I. (working on my FFL now). I love that one day you will get your certification but until then you will help those learn safety then pass them off to a certified instructor to take them further on their journey. Good stuff.

      Hello Kenny,
      Thanks for your kind words. I think it is very important to see positive content related to firearm safety. Good luck completing your FFL. If you have any questions about that process, hit me up via my Ig (frigeratorQ), Facebook(Strap House Customs) or website (straphousescustoms.com).

      CEO, Gunsmith & FFL
