The UTG Super Slim Picatinny Riser Mount features three slots to provide secure optics mounting. This riser mount is built with aircraft-grade aluminum for exceptional durability and strength. A unique side plate design uses a tension spring to quickly and securely attach the riser to the rail already on your rifle. To maintain the maneuverability of the rifle, this Picatinny riser features ideally-placed lightening cuts that reduce the weight of the mount. Designed to elevate optics above the rail for optimized sightlines, the UTG Super Slim Picatinny Riser Mount with 3-Slots offers a secure, easy-to-install platform for mounting optics.
