Sons of Liberty Gun Works P3 Recce .223 Wylde Intermediate - AR-15 Barrel - 16"

The P3 Recce in the standard 16-inch fighting rifle length — accuracy-oriented construction without sacrificing the reliability you need in a working barrel. The Sons of Liberty Gun Works P3 Recce at 16 inches delivers 416R stainless steel, nitride finish, and 3-groove polygonal rifling on an intermediate-length gas system, in the .223 Wylde chamber that handles both 5.56 NATO and .223 Rem without compromise.

The Sons of Liberty Gun Works P3 Recce Barrel is a 16-inch precision-oriented AR-15 barrel chambered in .223 Wylde, machined from 416R stainless steel with a nitrided finish and 3-groove polygonal rifling on an intermediate-length gas system.

Four engineering choices define this barrel's precision capability. 416R stainless steel delivers the corrosion resistance and tight grain structure that precision barrel makers have relied on for accuracy-first builds, outperforming chrome moly in both material consistency and long-term bore quality. Nitride finishing adds surface hardness and corrosion protection over the base stainless, extending service life in field conditions and under sustained fire. The 3-groove polygonal rifling geometry — developed from SOLGW's SPR Match barrel — minimizes point of impact shifts between ammunition types, reduces fouling accumulation, and delivers the projectile-to-bore consistency required for repeatable precision. The .223 Wylde chamber accepts both 5.56 NATO and .223 Rem, maximizing the ammunition flexibility available to a precision-focused AR-15 platform.

Compatible with mil-spec AR-15 lowers and intermediate-length gas systems. .750-inch gas block journal with deep dimple. 5/8x24 threaded muzzle optimized for suppressor compatibility.

416R stainless steel. Nitrided finish. 1:7 twist. Medium contour.

Built for precision patrol rifles, DMR configurations, suppressed AR-15 builds, and standard-length platforms where 416R stainless construction and polygonal rifling deliver a meaningful accuracy advantage.
