Cadex showed us a 3D printed prototype of this cool Extended Rail Mount in the ADS Inc booth at AUSA. At the USASOC Sniper Comp this week at Ft Bragg, they had a machined aluminum version. It attaches to a Knights Armament Rail to give you some additional rail real estate out in front of the sight.
These are available for unit and agency purchase through ADS Inc.
