The Quick Release Mount for AccuPoint Riflescopes from Trijicon fits riflescopes with 1" main tubes and features the patented BLAC lever system, which requires no manual adjustments to attain solid attachment on a Picatinny rail. This mount can be adjusted to accommodate desired eye relief by placing scope rings in four locations along the base. Simply remove the base screws, move the rings to a new location, and re-install the mount screws.
