Defesnive AR-15 Skill Builder Classes
Arm yourself with the techniques needed to become an expert with your AR-15 while also building realistic skills that can survive the test of a life-threatening encounter.
Defensive AR-15 Skill Builder 1
The AR-15 Skill Builder 1 (ASB1) course is the first step in learning the capabilities of the carbine as a defensive tool in close quarters. Take the first step to becoming an effective marksman with our professional instructors.
This course is perfect for beginner to intermediate shooters with the AR-15 platform who are interested in enhancing their abilities. This course is geared towards anyone looking to learn how to use the AR-15 platform safely, effectively, and reliably as a defensive platform. Students will become familiarized with the AR-15 rifle and will learn the basic gun-handling skills that are necessary to safely operate this weapon system.
You will also learn how to "zero" your rifle, administer multiple types of reloads, and handle malfunctions.
Defensive AR-15 Skill Builder 2
Our AR-15 Skill Builder 2 (ARSB2) course builds upon your techniques to become an expert with your AR-15. We will be shooting at up to 100 yards, shooting in unconventional shooting positions, addressing multiple adversaries, and more.
Our drills focus on maintaining the skills learned in ARSB1. We’ll also be introducing stress in a safe and controlled environment to help reinforce muscle memory and accurate shots in a short time frame.
All of our drills are designed to help you increase your accuracy and speed, and many of our students see a drastic improvement from the beginning of the class to the end. This defensive training allows you to be an asset, ready to protect yourself, your loved ones, and the community.
