This MIL spec PVS-14 eyepiece assembly has been machined to accommodate proper clearance when used with the MH25 eyepiece adapter. Compared to the standard MH25/ML19eyepiece this assembly increases the usable eye relief and interpupillary divergence, and decreases the perceived optical magnification to 1X. These improvements make the MH25 and ML19 compatible with any standard PVS-14 eyepiece accessory and more useful when helmet mounted.
