4.4-Inch Bronze Barrel
The AXIO 4.4 PRO features a precision-machined 4.4-inch bronze barrel. The bronze finish provides a premium, eye-catching contrast against the black frame while offering excellent corrosion resistance. This barrel length delivers an optimal balance between muzzle velocity, accuracy, and concealability. The longer barrel increases bullet velocity and provides a longer sight radius, resulting in improved accuracy and terminal performance compared to shorter-barreled models.
