AR15 2 Day Master Armorer and Build Course



This Class is a Condensed/Combined AR Armorer and AR Build Course with an added in Range Day.


This Course is tailored for those who want both Classes and Renge/Test Time. Students will build their "Box of AR15 Parts" into a reliable AR15 under a Gunsmiths supervision. YOU will bring your OWN AR15 components, and YOU will build the gun. I will watch and teach you. Unlike other Schools, we DO NOT require Students to take our other Class Offerings, to attend more advanced courses like this one. 


If you don't have a "Box of Parts" but have an ASSEMBLED AR15, you can bring an assembled AR and I will tear it down before class so you can reassemble it to proper specifications. Remember, just because your AR is put together, it does not mean it is put together and tuned properly.


The Class will be held in at a Private Site in Elkton, MD.


Student's who are interested in attending will be required to send me a detailed list of the components they have and a photographs of the components. I will need details on what parts are new and/or used. All components brought to the class MUST be approved by me first.


No tools required. I provide ALL of them. You may bring your own tools and gauges if you would like to use them.


Students MUST bring their own Ear Protection, Eye Protection, Minimum of 60 Rounds of Ammunition, and at least 3 Magazines. 


Class is for 5.56/.223, 9mm Luger, 6.5 Grendel, 6.8 SPC, 7.62x39, and .300 Blackout Caliber AR's ONLY

There will be loud noises during some parts of the course. There will be Air Compressor and Hammers being used, and on Day 2 we will be on the Range.


This course is a safety oriented but relaxed environment. The course is meant to be a fun and enjoyable learning experience with likeminded people. Your AR15 will be gauged and assembled during the course. It is possible that you will find a problem or something or something will fail a gauge test. If this occurs don’t worry, take a deep breath, relax, clear your mind, and then get back into the task at hand. The purpose of the course is not to show you how "junky" your AR15 is. The purpose is to teach you how to build and gauge it properly. You are free to bring your own spare parts or, if available you can purchase parts on site with a Check or Cash if you wish to repair any problem during the course that you may encounter. 


NO Pets are permitted! (Service Dogs are permitted, but they MUST behave)


NO audio or video recording devices are permitted without my permission. If you attempt to record and video or audio without permission, you will be asked to leave. NO REFUNDS!


NO cell or smart phone use allowed! You can bring a cell/smart phone to and inside of the course but it MUST be on silent/vibrate. I will NOT allow usage of cell/smart phones or texting during course. We will have periodic class breaks and phone usage is welcome during that time. If you have something important to use your cell/smart phone for during course you can go outside to text, email, instant message, skype, facetime, video chat, talk and the like. I WILL NOT permit phones to be out in the open during course.  


The student understands that ALL materials and information is protected and copyrighted. The student agrees to not duplicate or copy ANY information provided in the class or reproduce the material for their own classes and/or instruction. 


There are NO REFUNDS if you have an emergency and must leave course. Under LIMITED circumstances, I may waive fees to attend a future course. This is handled on a case by case basis and there are NO GUARANTEES.


There will be no discussions about how to violate firearm laws. 


There will be no trash talk of Internet Forums, Instructors, Gun Shops, Armorers, or Gunsmiths. That is NOT the purpose of the course. We are here to show you “A” way to do things that was developed through professional Gunsmith experience with the AR15.  I encourage all of my students and prospective students to take other courses if they have the time and funds. As an Instructor and Gunsmith, I never stop learning and I encourage others to do the same.

Large Frame AR's (AR10 Type) are not permitted in Classes of 2 or more Students, but I can schedule a ONE on ONE Class for Large Frame AR Owners. 


This course is conducted in a single room so please be mindful of your personal hygiene. I urge everyone to shower in the morning before attending and wear comfortable and freshly laundered clothing.
