Mark Heins, Deputy Director of Training

MarkMark Heins grew up on a farm in central Nebraska where he developed a fondness for firearms. Hunting and spending large amounts of time practicing helped develop his skills. While in his junior year of high school, Mark started tinkering and really learning how firearms worked. Joining the military a few years later added to his knowledge base greatly. Becoming an instructor and trainer enabled him to go on to bigger and more exciting ventures.


While stationed in Washington State, he became a Combat Airman Skills Training Instructor. He was exposed to multiple facets of shooting, both combat, and self-defense. This was also the stepping stone for firearms instruction outside of the military. He attained over 5,000 teaching hours in the field. During that time, he started reconditioning and refurbishing old and damaged firearms. Having access to a gun store nearby that was able to trade Law Enforcement confiscated firearms for Glock’s with the local sheriff’s departments, made a unique opportunity to purchase and restore firearms people saw rarely. This became a sideline business for him.


Retiring from the Air Force in 2011, he became an NRA Firearms instructor as well as an NRA Range Safety Officer. Mark then started teaching the Oklahoma Self Defense Act shortly thereafter. He is a graduate of Canadian Valley Technology Center Gunsmithing course. At Wilshire Gun he provides personal instruction, gun fittings, Self Defense Act classes well as NRA course instruction. Mark also developed owner courses, based off manufactures armorer’s courses for Glock, Smith &Wesson, and AR-15 platforms, as well as a gun cleaning class to heighten firearm owner skills. Currently, he serves as Deputy Director of Training.
