Ballistic Advantage 16" 6.5 Grendel SPR Mid-Length Barrel – Precision in a Compact Package
The Ballistic Advantage 16" 6.5 Grendel SPR barrel delivers a premium solution for AR-15 builders who demand accuracy and durability in a manageable profile. Designed for those who want the ballistic performance of 6.5 Grendel in a mid-length package, this barrel is perfect for precision shooting, hunting, or tactical applications.
Crafted from 416R stainless steel and finished with a bead-blasted exterior, this barrel not only looks sharp but resists corrosion in all conditions. The Special Purpose Rifle (SPR) profile strikes a balance between rigidity and weight, offering enhanced accuracy without being front-heavy.
With a 1:8 twist rate, it reliably stabilizes the most common 6.5 Grendel bullet weights (100–130 gr), while the mid-length gas system ensures smooth recoil and cycling. The barrel is threaded 5/8x24 at the muzzle, making it ready for your favorite suppressor or brake, and features a Nickel Boron-coated M4 feed ramp extension for improved reliability.
Backed by Ballistic Advantage’s reputation for craftsmanship and performance, this barrel is built for shooters who won’t settle for less.
