About Us

What We Do

Although we are a multi–Certified Firearms Instruction Company, the majority of our training involves handguns. We are a Certified State of Nevada and Clark County Concealed Carry Weapon (CCW) Instructor. Handguns are only built for one thing, “personal protection”, they really aren’t good for anything else.  If you are going to have a handgun with you or keep one at home, you need to be trained not only in the operating and safety functions, but also when you can use it as well. As with all Firearms you should only use it as a means of last resort to protect yourself, your family, and your property.  

How do we do it?

We do this by using applied methods of training from both the United States Concealed Carry Association (USCCA) and the National Rifle Association (NRA) along with decades of experience including law enforcement. ZRANGE is always creating new courses and methods for training our students. ZRANGE is the first and only Certified Firearms Instruction Company in Las Vegas to have an online educational course called “I’m 2A”. We saw the need for this type of educational training because of the lack of it being available. All of us have busy lives, so we created our educational training courses for those who can’t seem to find the time to train. We took time out of the equation, so you can learn when you have the time and not just when we are available to train with you. Although our courses are detailed, we strongly recommend that you seek out training with a Certified Firearms Instructor in your area. Owning a Firearm is a wonderful way to protect yourself and your family, however, it is still a dangerous weapon and if you aren’t trained properly, it could be used to cause injury or death to someone you love.  

Our team


Hey there, I am Cam Oliver, the Senior Firearms Instructor at ZRANGE LLC. I have over fifty years of Firearm experience and thirty years of carry experience both in law enforcement and as a citizen. I am a dual Certified Firearms Instructor with both the USCCA (United States Concealed Carry Association) and NRA (National Rifle Association), 1 of 125,000 in the United States.

Those of us who both own and carry a Firearm do it because we know there is a need to be able to protect ourselves and our families. Working in law enforcement, I have had the displeasure of meeting very evil people. I carry a Firearm to protect myself and my family from them. I am an advocate of the 2nd Amendment. The United States of America is 1 of 175 countries in the world that allows its citizens to own a Firearm for protection. As a Certified Firearms Instructor, it is my duty to teach you Firearm Safety, Firearm Responsibility and lastly the use of a Firearm in Self Defense as a means of last resort. Although I am both Certified by USCCA & NRA I do not teach either prescribed course. I teach a course using the best of both and practical application based on decades of experience and training.

As a Firearms Instructor, I am not going to train you how to take another person’s life. I am going to train you in the responsibilities of how to be a safe and responsible Firearms owner. Whether you carry a firearm on your person or keep it at home, safety is your responsibility. My duty is to ensure that I provide you with the knowledge and empower you with the experience to continue your journey of being a Firearm Owner. We chose our company motto carefully “I train not to be a hero, but I refuse to be a victim.”  I do not ever want you to have to use your Firearm, but I do not want anyone to be a victim of someone who has any weapon, especially a Firearm. Nor do I want anyone to be injured or killed due to lack of training or unsafely handling of a Firearm.


Hi, I am Gina Oliver, the Executive Administrator for ZRANGE LLC. For the last fifteen years I have worked for some of the largest Hotels/Casinos in Las Vegas. I am proud that I started in the resort industry at an entry level and worked my way up to management. When Cam got injured and we both knew he would never go back to work or at least not to any position he would want. I encouraged him to become a Certified Firearms Instructor. We decided to form our company as a Women’s Minority Business, as I will be handling the administrative business responsibilities and Cam will focus on Firearm training and courses.

While we are somewhat of a newer Firearms Instruction Company and smaller than others, we are totally family owned and operated as well. One of the things that I have enjoyed the most since starting our business is meeting and making friends with so many of our students. It is important to us that no matter how large our company grows we want to maintain a sense of being a family-owned business. We want our students to feel they can contact us anytime, get advice or to simply just stay in touch with us as friends.


Cameron-Dean Oliver (Kamalei) is the youngest of our three sons and a Director of Operations for ZRANGE LLC. While Kamalei is not a Certified Firearms Instructor, it is because he is currently serving in the United States Air Force as a Military Police Officer. His full contract ends in May of 2024 when he will be moving back to Las Vegas. He will continue to serve our country by becoming an Active Reservist in the military and his career in law enforcement. He will be working in the family business becoming Certified Firearms Instructor both with the USCCA and NRA. Learning the family business will ensure that those of our students who rely on our training will continue to be trained by our family when the day comes that Cam & Gina retire.
