ERA-TAC USL Aluminum & Stainless Steel Riser Mount for Aimpoint COA 39mm/1.54" Lower-Third Centerline T6121-0039

The ERATAC USL (Ultra-Slim-Lever) Optic Riser Mount delivers a rock-solid, German-engineered quick-release solution designed to interface seamlessly with modern micro reflex and red dot sights. Meticulously machined out of a solid block of high-grade 7075 aircraft aluminum, this mount features fully tempered stainless steel functional moving parts to survive harsh, heavy-recoil weapon environments. The core engineering breakthrough centers on the Gen 2 Ultra-Slim quick-release layout; when closed, the operating lever rests perfectly flush with the body of the housing. This entirely eliminates snag points on uniforms, brush, or weapon controls like top-loading charging handles. Equipped with an adjustable clamping system with an internal locking pawl, it achieves a secure, 100% shock-proof seating against Picatinny rails that delivers impeccable return-to-zero repeatability when taking the optic on or off. With a precise 39mm (1.54") centerline height profile, it acts as an elite Lower-Third co-witness riser option to hoist your Aimpoint-compatible footprint red dot into an optimal, clean field of view over your tactical setup.
