Lightweight Fluted 416R Stainless Steel Barrel

This barrel is made from super durable and heat-resistant 416R Stainless Steel and is available with either a black nitride or raw stainless steel finish. The barrel is also fluted, which decreases its weight, and gives the barrel more surface area for better heat dissipation. The barrel weighs 2.04 lbs.

5R Rifling

The Juggernaut Tactical 18-Inch 5.56 AR-15 Stainless Fluted Barrel has a 5R rifling pattern, which incorporates 5 grooves, with different angled cuts that make the barrel more accurate than a conventionally rifled barrel. The twist rate on this barrel is 1:8. Moreover, this barrel is threaded with a 1/2”-28 thread pitch and has a mid-length gas port placement.
