The Noveske SPR Barrel 5.56 18" DDF brings Noveske’s stainless match-barrel pedigree to AR-15 builders who demand precision and durability. Built from 416R stainless steel with a 1:7 twist, this 18-inch barrel uses an extra thicc contour with disruptive deep fluting to balance rigidity and weight. A hand-polished Noveske proprietary match chamber and extended feed ramps are paired with a pinned 0.936" low-profile gas block and a threaded muzzle, giving you a ready-to-run, rifle-length gas system barrel designed for consistent accuracy.

This SPR configuration is ideal for shooters looking to stretch the legs of their 5.56 or .223 Rem platforms for precision range work, practical competition, or training-focused builds. The bead-blasted stainless finish and 60-degree crown support long-term reliability while maintaining a clean, professional look. Backed by Noveske’s reputation for meticulous machining and tight quality control, this barrel is a strong foundation for a premium AR-15 upper.
