    Outstanding barrel

    Posted by Anthony Ortega on October 8, 2024

    Bought this barrel to replace a Rosco bloodline spr barrel. After 300rds during training it would start to pop from the heat. Got tired of it and bought this kak spr barrel. Groups have been amazing. The heat dissipates phenomenally no pops after firing 300-400rds definitely a hard use barrel. The profile is definitely heavier than the medium profile of the Rosco but it’ll lighten up after a few training sessions. Definitely recommend this guy for your spr build shoots amazing suppressed as well.
