The Noveske Infidel BBL 556 13.7" SS BLT is a precision 5.56 NATO rifle barrel built around Noveske’s stainless Lo-Pro gas block design. Crafted from 416R stainless steel with a bead-blasted silver finish, it uses a 13.7" threaded barrel with a 1/2x28 muzzle, mid-length gas system, and pinned low-profile gas block for dependable function and smooth recoil impulse. A hand-polished Noveske Match chamber and extended M4 feed ramps support reliable feeding and consistent accuracy.

This barrel is ideal for building a compact AR-15 style rifle focused on accuracy and balance for range work, training, or general-purpose use. Each barrel is individually serialized and ships with a matched gas tube and headspaced bolt, simplifying assembly and helping ensure long-term reliability. It reflects Noveske’s reputation for careful machining, tight tolerances, and thoughtful barrel design.
