In this video with Russell Phagan (Sinistral Rifleman) of KE Arms we discuss how to optimize the KP15 9mm PCC but also address a lot of what and how you should build an AR15 PCC, KP15 based or not.
I've been competing in the action shooting sports since 2002. I believe competition shooting to be an excellent way to build gun handling and marksmanship skills and encourage all gun owners to seek out some form of competition shooting. Anyone can become reasonably good at it if they devote the time and resources to do so. Winning, while nice, need not be your goal; bettering yourself through the pursuit of excellence is something we all can achieve.
