Sons of Liberty Gun Works Precision SPR 18" 6mm ARC Barrel – AR-15 Platform

The SOLGW Precision SPR 18" barrel in 6mm ARC is engineered for shooters who demand long-range accuracy from an AR-15 platform. The 6mm ARC cartridge delivers superior ballistic coefficients and reduced wind drift compared to traditional 5.56 NATO, making this barrel an excellent choice for precision rifle applications, varmint hunting, and extended-range target work. The 18-inch length provides an optimal balance between velocity retention and maneuverability.

Constructed from 416R stainless steel and finished with a durable nitride treatment, this barrel offers consistent accuracy and corrosion resistance. The SPR profile maintains rigidity for precision shooting while remaining practical for field use. Installation follows standard AR-15 barrel installation procedures. Compatible with standard AR-15 upper receivers and bolt carrier groups; requires a 6mm ARC bolt. Shooters should verify headspacing with proper gauges during installation.
