You know the barrel of your AR-15 is the heart of your system. If you put a lot of rounds through your rifle, in the field, or at the range, you want durability to last a lifetime without sacrificing accuracy. Ballistic Advantage’s AR15 18-inch barrel offers both while still keeping your suppressor options open.

Serious steel

Ballistic Advantage manufactures their 18” AR barrel from 4150 CMV steel, an alloy known for handling extreme temperatures. Even at fully automatic rates of fire, a barrel made from 4150 won’t fail. It’s also ready to accept suppressing gear—an important consideration if your AR-15 is your home-defense partner.

Drive those tacks

The AR-15 18-inch barrel from Ballistic Advantage is rated to offer sub-Minute of Angle accuracy. That means no excuses—if the shot groups on your targets look more “socially distanced” than up close and personal, it might be time to reevaluate how much time you spend at the range working on your form.
