A Better
Resource for
Every Shooter

At HexCore Mounts, we know the firearm world comes with a language of its own.

From cartridge names and action types to optics, accessories, and safety terminology — there are a lot of terms that get thrown around. For experienced shooters, that language may feel second nature. For newer gun owners, it can feel like a lot to take in.

That's exactly why we created the HexCore Mounts Gun Terms Glossary.

The firearm space is full of specialized language, abbreviations, and platform-specific terms. It's common to hear words thrown around — but not everyone starts out knowing exactly what those mean.

At HexCore, we believe better understanding leads to better decisions.

The more informed a shooter is, the more confident they can be when it comes to training, gear selection, firearm setup, and responsible ownership. Our glossary is one more way we can support the community beyond just building mounts.

The HexCore Mounts Gun Terms Glossary was created to be useful whether you are:

New to firearms and trying to learn the basics
Researching rifle and handgun terminology
Comparing calibers or platform features
Learning the difference between common accessories and components
Looking for quick definitions without overly complicated explanations

We wanted this resource to be straightforward, useful, and easy to reference whenever you need it.

Our glossary covers a wide range of firearm-related terminology — all in one place, without having to dig through forums or piece together definitions from multiple sources.

Calibers & Cartridges
Common rounds, sizing, and what they mean for your platform

All the shorthand the industry uses — decoded

HexCore Mounts was built around the idea of creating purpose-built solutions for the modern armory — but we also believe in creating useful resources for the people who support our brand.

That means building more than products.

It means building a better experience for the firearm community by helping shooters learn, organize, and move forward with confidence. Our Gun Terms Glossary is part of that mission.
