Precision Engineered Performance. Tactical Maneuverability. Thermal Stability & Service Life.

Engineered for individuals who demand balance of accuracy, heat tolerance, and manageable weight from their rifle, the 5.56x45mm NATO Medium Profile Barrels from TRYBE Defense deliver the ideal combination of tactical maneuverability and thermal mass. Precision machined from 4150 CMV steel, heat-treated to MIL-SPEC hardness, and finished with a black nitride surface treatment, these barrels offer superior performance under sustained use and harsh environmental conditions. The medium profile balances weight and carry comfort with thermal performance, making it suitable for high-volume shooting without unnecessary and unwieldy mass.

A quality aftermarket barrel is the single most important upgrade you can make to increase the accuracy, consistency, and overall performance of your AR-15. The 5.56 barrel chambering safely accommodates both .223 and 5.56, but it is optimized for 5.56x45mm NATO ammunition.

All TRYBE Defense barrels undergo rigorous quality checks and are held to the highest of standards. Each batch of TRYBE Defense barrels is inspected nearly 70 times throughout the manufacturing process, to include 100% inspection of headspace to ensure compliance with SAAMI Specification. Each barrel is also air gauged after rifling and is held to .0002" concentricity of the bore.

The TRYBE Defense Medium Profile AR-15 Barrel chambered in 5.56x45mm NATO is a professional-grade component designed to elevate the performance of any rifle it’s paired with. Invest in quality where it counts. Whether for precision work, tactical applications, or high-volume shooting, this barrel delivers enhanced mechanical precision, gas efficiency, and structural resilience — with the metallurgy and engineering to back it up.
