Changing lenses is a snap with the Hawk.  Pilla’s patented ‘Snap Tec System’ allows a shooter to quickly respond to changes in lighting conditions by swapping lenses in literally just a matter of seconds.  A minimal nose is used to provide superior performance.  Additionally, the amount of lens above the nose offers a window for vision.  The Hawk features a supple, silicone, Crystal nose for minimal visual interference.
