Why Faxon Firearms Has Become an Industry Standard

Founded by engineers with aerospace and defense backgrounds, Faxon Firearms is now a leading manufacturer of precision firearm components, renowned for turning out innovative, dependable, and obsessively engineered parts. Known for everything from barrels and bolt carrier groups to complete upper receivers and Glock parts, Faxon doesn’t just follow industry trends—they set them.

As gun writer and former SOF weapons specialist Chuck Pressburg said on a recent podcast:

“Faxon barrels are one of the few I recommend out of the box without modification. They’re light, they’re straight, and they shoot like a dream.”

Let’s break down the best-of-the-best from Faxon Firearms in 2025.

1. Best AR-15 Barrel: 16” Gunner Profile (5.56 NATO)

Why Faxon Firearms Stands Out

Faxon thrives because it manufactures in-house, controls its tolerances like a boutique watchmaker, and delivers design-first components for serious shooters. Whether it’s innovative barrel profiles, precision BCGs, or factory-built optics-ready pistols, they consistently balance engineering with user-driven performance.

They also back their products with a Lifetime Guarantee and a stellar customer service team that’s still run like a family business.
