Mfg Item #: SIARSFBARREL
The SI Strike Fighter Barrel 10.3" is inspired by the tried and true Mk18 barrel, but significantly updates it for increased performance, longevity and accuracy. The improvements start with the barrel profile. The gradual transitions increase strength and reduce heat related differential expansion, allowing for greater shot to shot consistency like a heavier contour barrel, while still weighing less than an equivalent length government profile. Perfect balance facilitates ultra fast close in transitions, but has the weight and stiffness for fine accuracy shot after shot. The .223 Wylde chamber and 1/8 twist rate contribute to greater accuracy across a broad range of ammunition.
