Multi-Tier Picatinny Riser Mount for EOTech XPS style optics Allows you to attach optic and light/laser/accessory closer together and on the same mount for improved weapon handling and faster target acquisition, especially on SMG/PDW type weapons with limited rail space Increases optic centerline to 2.91", ideal for for the modern warfighter using NODs / helmet mounted earpro/ etc. The higher sight picture allows the operator to roll the firearm from left eye to right eye without changing grip (a must for negotiating corners in CQB) and maintaining a "plates forward" posture to threats. Integrated pass-through channel for cable management Dual precision machined recoil stops Aluminum Alloy Construction New Gen 2 version offers the following improvements: Shortened rear profile allows for magnifiers to be installed as close to the optic as possible while also reducing overall weight Larger cable management opening Strategically lightened, reinforced neck permits lower weight without sacrificing strength Pass-through holes for direct attachment of laser to riser, reducing weight and improving accuracy by eliminating the need for quick release mount bases
