This is a PVS-14 Night Vision device. This comes complete with everything you need to start using it right away. A skull crusher, ryno mount, and J-arm. The stated FOM on the spec sheet is 1824 and I have the original spec sheet if needed. The tubes inside are the Photonis Echo WP tubes. It has a ODG Ranger wrap on it to protect the housing. You can email me at Keaton.m.sims@gmail.com if you need more pictures or specs. Tubes are Blemish Free.
