Cutting through

The OCAW MK11 Polarstar is the ultra light weight, HPA configuration of the MK11 series, built to deliver a fully integrated and finely tuned HPA system out of the box. This build excels at accuracy and through volume of fire, cutting through wind, brush, and other environmental factors that would normally throw off the trajectory of a BB from a standard Airsoft gun.

Ambidextrous controls.
This light construction brings the renown firearms company Radian into our build, providing control for both left and right handed players.
