NSW 15.1 RECCE Barrel Barrel

The 15.1" NSW Recce Rifle Barrel is a purpose-built, match-oriented profile engineered to deliver the balance of compact maneuverability and extended-precision performance demanded by modern recce and special-operations platforms.

Key features

Length: 15.1 inches - short enough for close-quarters handling, long enough to preserve velocity and stabilize heavier 5.56 projectiles at extended ranges.
Chambering: 5.56×45 NATO for broad ammunition compatibility and reliable feeding with common magazines.
Twist: 1:7 twist to reliably stabilize a wide range of bullet weights.

Performance & intended use

This barrel is optimized for operators and precision shooters who need a compact platform that still extends effective, accurate engagement distances beyond typical carbine ranges. It provides increased muzzle velocity relative to shorter carbine barrels, improved bullet stabilization for heavier projectiles, and predictable harmonics when used with modern optics and suppression. Ideal for recon, designated marksman, and mission-configurable patrol builds where weight and length must be balanced against terminal and ballistic performance.
