This MIL spec PVS-14 eyepiece assembly has been machined to accommodate proper clearance when used with the MH25 V1 and ML19 V1 eyepiece adapter. Compared to the standard MH25/ML19 eyepiece this assembly increases the usable eye relief and interpupillary divergence, and decreases the perceived optical magnification to 1X. These improvements make the MH25/ML19 compatible with any standard PVS-14 eyepiece accessory and more useful when helmet mounted.
