Machined aluminum and anodized replacement shroud gives you a "Ported" design look with a natural flow, allowing exposed barrel views with layered machined levels. This is designed for the "Shorty" GK1 version and to be used with RED Dot and does not have front sight. (Krazz Cool "Shorty" is a different length than Huben factory shorty so please specify which one for order)
 
Design and made by me here in the US
