SureFire Ops Core Helmet Rail Mounts. Utilizing MRO's (Modular Picatinny) rails the OPPS allows quick attachment of the device in forward or backward configurations. The OPPS mounts a low-rise night vision monocular device and a magnified long-range magnifier which can be used with long-range surveillance systems e.g. a hog hound scope. It is designed for mounting to standard helmet-mounted rails or panels. Equipped with a single clamping point the OPPS provides a very stable mechanism for mounting a laser/imprinting device. All mounting hardware and a detailed instruction manual are included.
