Knight's Armament SR-25 A3 6.5 Creedmoor Rifle System 22" Dimpled Barrel - 20 Rd

The Knight’s Armament SR-25 A3 6.5 Creedmoor Rifle System is a refined evolution of the iconic SR-25 lineage, engineered for precision long-range engagement, modular adaptability, and uncompromising battlefield reliability. Chambered in 6.5 Creedmoor, this advanced rifle system is designed for shooters who demand consistent accuracy, superior ergonomics, and mission-ready performance across extreme conditions.

At its foundation is a 22-inch 5R cut-rifled 416R stainless steel barrel with a dimpled hybrid medium profile. This configuration enhances barrel harmonics, improves heat dissipation, and delivers exceptional consistency shot after shot. The 1:7.5 twist rate is optimized for modern long-range projectiles, maximizing stability and ballistic efficiency at distance.

The SR-25 A3 features a fully ambidextrous control suite, high-pressure E3 bolt system, and refined receiver geometry for enhanced reliability in both suppressed and unsuppressed firing conditions. Its URX6 handguard provides a rigid, anti-rotation mounting platform with full-length MIL-STD-1913 rail integration and M-LOK compatibility, enabling extensive customization. Combined with a drop-in two-stage trigger and modular control interfaces, this rifle is built for precision shooters who require adaptability without sacrificing durability or performance.
