Springfield Echelon + Aimpoint COA: No Wiggle, No Wobble
This video details the installation of an Aimpoint COA optic onto a Springfield Echelon pistol, highlighting the 'ski boot' like locking mechanism of the COA system. The presenter emphasizes the secure, no-wiggle, no-wobble fit achieved by this mounting method, which uses rear sight screws to secure the optic.
