The A.R.M.S. M16A1A2 Extended Scope Mount is a one-piece aluminum Picatinny rail designed to give classic M16A1 and M16A2 rifles a solid, repeatable platform for modern optics. Machined with a wide TV-shaped channel through the center, it preserves access to the rifle’s iron sights while the self-locking thumbnut anchors securely into the carry handle for a consistent zero. The matte black finish keeps reflections to a minimum and blends cleanly with standard service-style uppers.

This mount is ideal for shooters who want to add red dots or magnified scopes to fixed carry-handle AR-15/M16 uppers without sacrificing the ability to run irons. Its extended rail length supports flexible eye relief and a broad range of ring and optic footprints compatible with NATO STANAG and Weaver-style interfaces. Whether you are refining your rifle for range work, training, or general-purpose use, this mount reflects A.R.M.S.’ long-standing reputation for practical design and dependable machining.
