The Proof Research 7mm Sendero barrel is a precision rifle barrel built for long-range hunters and competitive shooters who demand both accuracy and durability in their bolt-action setups. At 20 inches long with a 1:8 twist rate optimized for the 7mm cartridge, this carbon-fiber barrel strikes the balance hunters need—manageable weight and fast handling without sacrificing the ballistic performance that matters at distance. The Sendero contour provides a moderately heavy profile that resists heat soak during shooting strings while keeping overall rifle weight reasonable for field carry.
Proof Research's carbon-fiber construction reduces weight without compromising rigidity or shot-to-shot consistency. The barrel threads at 5/8-24 (standard for many modern suppressors and muzzle devices) and is ready for a gunsmith to install on your Stiller or other precision bolt action platform. Whether you're setting up a new build or upgrading an existing rifle, this 20-inch tube delivers the precision tube quality Proof is known for, with the weight savings carbon fiber brings to the hunt.
This is a bare barrel—installation and headspacing require a competent gunsmith. Pair it with quality reloading practices and optics suited to your distance, and you'll have the foundation for a rifle that shoots as far and as accurately as your skill allows.

Frequently Asked Questions
What rifles does this barrel fit?
This is a bare barrel designed for installation on Stiller and other precision bolt-action platforms that accept a 7mm barrel. Proper headspacing by a qualified gunsmith is required during installation.
Can I use this barrel with a suppressor?
Yes. The 5/8-24 muzzle thread is the standard for most modern rifle suppressors. Your gunsmith can install a compatible muzzle brake, suppressor adapter, or direct-attach suppressor during barrel installation.
Is this barrel ready to shoot out of the box?
No. This is a bare barrel that requires professional installation, headspacing, and timing by a qualified gunsmith before it can be used on your rifle.
What's the advantage of carbon fiber for a hunting barrel?
Carbon-fiber barrels weigh significantly less than steel while maintaining the rigidity needed for accuracy. The Sendero contour adds some heft to manage heat, making this a balanced choice for long-range hunting where both accuracy and field handling matter.
