Guntology has been in operation since 2021. We are a Texas-based company founded by two lifelong friends, Samuel Vester and Sebastian Esquivel. We have been lifelong firearms enthusiasts and wanted to create a company to provide you, our customers, with gear that we would, and do, use ourselves.

Based proudly in Laredo, we offer a curated source of the best products that we personally vouch for. We stand behind the products that we sell, which are made in the USA. As a testament to our faith in our products, we are willing to offer a lifetime warranty on everything we sell.

Guntology is more than a business to us. This began as a friendship built through a shared passion for firearms and the freedom they represent. We found, over time, that the best way to get the kinds of products we wanted was to source them ourselves.

This business began with the Teal Blue Bravo PDQ ambidextrous bolt release. This first product, developed by one of our friends, Bill Brotherton, symbolizes what we seek to do here at Guntology. It’s a part that fine-tunes the AR shooting experience, makes the gun work better for more people, and, vitally, is built to last a lifetime.

If you have any questions for us, please do not hesitate to reach out. At the end of the day, we’re fellow firearms enthusiasts, and we’d love to talk with you!

Our Team

Sam on Tank



Samuel Vester has been a lifelong firearms enthusiast. When we say lifelong, we mean lifelong. This guy was shooting local IDPA matches at 9 years old! Born and raised in Laredo, Texas, Sam spent most of his time outdoors, where he started implementing pistol shooting, long-range shooting, armorer courses, and much more. Sam founded Ronin Armory in 2016 and is also Co-Owner of the Arena Gun Club in his hometown. Sam is an experienced armorer, certified by Sig Sauer, and Smith and Wesson, just to name a few. He is also an advanced cerakote applicator and a firearms instructor. Sam has trained with some of the biggest names in the industry throughout the years.

Sebastian with rifle in hand



A lifelong firearm enthusiast, Sebastian Esquivel got hooked with an old browning .22 lever action when he was around 8 years old. His father and older brother, both avid hunters, got him interested and taught him the basics of firearms. In 2016 Sebastian founded Daily Gun Dose, one of the most influential gun pages in the US. Sebastian has a background in sales and marketing in the energy industry and international political campaigns. Around 2016, Sebastian partnered up with Samuel Vester and now co-owns and runs Ronin Armory and Guntology with him. Sebastian has attended multiple pistol and rifle courses and is certified by some of the biggest names in the firearms industry as an armorer, Advanced Cerakote applicator, and firearms instructor.
