The “Why” Behind the Barrel

When starting a build, the crucial question to consider as you select components is “why.” If you’re like us, If your “why” is needing something accurate, durable, and reliable, this is the barrel for you. While having these barrels made, we demanded a barrel that would not limit the shooter in terms of accuracy. We went with a 13.7" barrel to be able to pin and weld some of the most popular muzzle devices (SOLGW NOX & Surefire Warcomp) to allow us to stay within a legal 16" barrel length and keep our builds lightweight. Finally, we wanted to make sure we focused on durability. The end-results of our efforts is a barrel you can count on to hit what you want, when you want, without compromise. 

Quality Materials, Quality Control

Material selection matters in a barrel. We decided to craft the barrel out of 416R Stainless steel to ensure peak accuracy. The reason why was simple – Accuracy matters both at the range and in the real world. That said, this 416R stainless barrel can handle the most adverse environmental situations and still be used in high-precision situations.

These barrels were made with stringent quality control and have one of the best Nitride finishes that you can find on a barrel. The finish provides superior corrosion resistance as well as a clean look.

Versatile and Dependable

We chose a 1:8 twist so that these barrels could be used with the majority of ammo grains. The bottom line is this, if you are looking for a highly reliable and accurate barrel, go with the Dirty Bird 13.7″ 5.56 NATO Midlength Length 416R Barrel.

Barrel Material: Domestically sourced 416R Stainless Steel
