Product Overview
MonoLift™ AMR Riser - Derived from our MonoLift Riser on the 2022 UK MoD contract for the L143A2 MCX-SPEAR LT service rifle. The MonoLift AMR Riser was designed for another mil unit to bring the Sig Sauer® Romeo 8T-AMR™ system to a 1.93" optical center height and also increase nthe distance of the magnetic reticle switching feature by 0.200" compared to a standard spaced pic rail. The rear deck of the MonoLift AMR extends above and beyond the charging handle giving it up to an additional 1.382" of eye relief over the standard MCX upper receiver. The MonoLift AMR Riser is also at home on various other platforms with many other optic, magnifier, and even elevated laser combinations when reversed. The MonoLift Riser utilizes the proven Scalarworks® FUSE™ mounting hardware. Optics are not included.
