AMTAC Shooting’s owner and lead instructor is Bill Rapier. He is recently retired after twenty years in the Navy, where his duty assignments included several years at SEAL Team 3 and over 14 years at Naval Special Warfare Development Group. Positions held include assaulter, breacher, sniper, team leader, troop chief and military working dog department senior enlisted adviser. He has always been an avid shooter and is heavily involved in combatives.


Centurion Arms LLC is happy to announce the AMTAC rifle and pistol collaboration. We have known Bill for over 20 years now and with confidence say he is one of the best people we know. Bill is no doubt one of the very best instructors there is on the open market for training. With his back ground and knowledge he is easily the most combat experienced instructor available today anywhere. We are VERY happy to be working on his Carbine and Pistol collaboration.

    First, let me start this review by thanking the Centurion Arms team for their customer service that included proactive communication from the time my order was placed.  Second, the personal touches throughout the buying process that included the hand written "Thank you!" note that I received in the shipping box was very much appreciated.  Lastly, I could not be more pleased with my Centurion Arms - AMTAC edition rifle because it exudes quality.

    This is a great AR package Monty and Bill!  Thank you!
