NOTICE: This custom lens protector was originally designed for pressure fit for Evolution Gear DR Gen3 1-4X Mil Spec Ver. (Perfect Edition).
However, it also works for standard Blackcat Specter DR 1x-4x by means of simply using heat shrink wrap to keep lens protector in place in front of the DR's lens itself, given there is a 8~10mm lengthened tube in front of actual optics' lens to prevent shock wave from cracking the optic's actual lens. You get the idea.

Features:

• - Polycarbonate lenses withstand 500 fps or above point blank
• - Laser cut 1.5mm hight impact strength lens
• - Pressure fit
• - Clear lens (After removing blue film)
