The search is over ! The AIMPRO Tactical Co-Witness System was developed in direct response to our customer's requests for a true shotgun co-witness system that would accept any off-the-shelf M4/AR-15 flip up sights in conjunction with the use of a modern red dot or holographic optic.
All our Co-Witness System Guns are built on the Mossberg® M590A1 heavy walled barrel platform.
We manufacture the front picatinny rail sight base from solid steel stock. Machined to Mil-Spec standards, it is high temperature silver soldered/brazed to the barrel. The base of the rail is relieved to reduce weight without sacraficing strength.
The 18.5" Co-Witness shown here has a parkerized finish and is fitted with a Mesa Tactical Stock and factory forend. Shown with GG&G Flip up sights
This Co-Witness sports an AIMPROTactical heavy barrel heat shield, Mesa Tactical Endine Stock and Hogue Forend in OD Green. The receiver and heat shield are finished in OD Green XCOAT to match.
A 20" Co-Witness with Hogue Stock Set and optional heat shield in parkerized finish.
