Be the go-to expert and build custom ARs that your buddies will drool over!

This course will take you from start to finish and you will know everything about these firearms and how to maintain and customize them. Having a rifle that works when you need it may be the difference between life and death.  If you dont know the information covered in detail in this course, you can easily waste thousands of dollars on parts that dont work and build rifles that just arent reliable. 

First, Ken Brooks will take you through a complete disassembly and reassembly of the rifle down to the last part making you familiar with all the parts of the rifle.  Master Gunsmith Bob Dunlap then helps you achieve complete understanding of the Design, Function and basic repair of the AR-15 platform. Understanding how the AR-15 and its clones function, including how the unique gas system works, is critical. Complete disassembly and reassembly, lubrication, maintenance, feeding, troubleshooting, solutions, and repairs are all explained and shown in eye opening detail, along with what critical spare parts are needed to keep on hand.

Bob then goes through the complete process of building up rifles assembled from parts kits from several different manufacturers. He shows you the problems and pitfalls to avoid. He covers parts identification, installing and fitting all the parts, headspacing the barrel, final assembly, test firing, and tuning. Bob teaches you step-by-step how to turn the existing trigger system into a target trigger.  He uses oversize mock-ups so you completely understand the critical positive-neutral-negative hammer sear relationships and are able to create a safe, light, and crisp trigger pull.

Your next instructor is Sgt. Mark Foster. He has over 30 years of Gunsmithing experience and is a 20 year veteran of the Sheriffs Department, where he is the Chief Armorer and a Training Officer. Mark shows and explains to you numerous examples of triggers, grips, optics, lights, rails, barrels, stocks, muzzle brakes, compensators, flash-hiders, sights, handguards, gas systems and more.

For each category he outlines what works well, tells you what to avoid and explains why. His daily field experience, combined with his armorer experience working on fellow officers weapons, gives him inside knowledge on the reliability and functionality of each of these options.  He has seen first hand what works and what doesnt and will help you avoid mistakes.

After reviewing the many available accessories thoroughly, Mark will show you how to build a variety of mission-oriented ARs and explains what components he chooses for each and why. He goes through the process of tailoring the AR for: CQB, general hunting, SWAT, 3-gun, varmint hunting, home defense, and plinking, just to name a few. In addition to showing and demonstrating the tools, he demonstrates step-by-step how to change a barrel and install a free-floating handguard.
