Description
The DSI 5.56 NATO AR-15 Barrels are precision-manufactured for builders seeking dependable performance across a wide range of AR-15 configurations. Each barrel is constructed from high-quality chromoly or CMV steel and finished with a durable nitride treatment for enhanced corrosion resistance and long service life.
Available in multiple lengths, gas system options, and barrel profiles, this lineup supports compact AR pistols, non-NFA builds, SBR platforms, and full-length rifles. SOCOM profiles deliver rugged balance for tactical use, while the HBAR option provides increased mass to reduce barrel harmonics and maintain accuracy during sustained fire.
All barrels feature M4 feed ramps, standard .750″ gas block journals, and threaded muzzles for compatibility with common muzzle devices. Proudly manufactured in the USA, DSI barrels meet strict quality and dimensional standards for professional and enthusiast builders alike.
