Madhouse Design's Gun Control System is the only "gun control" that works! Our GCS allows you to mount a single pistol or multiple pistols in an efficient and organized manner. It is compact, solid, and can be customized to your needs. The pistol mount pin is 303 stainless steel with a soft rubber over-mold to protect your weapon. The pins are interchangeable and will accommodate .22 to .45 caliber pistols. The swivel body locks in 7 positions at 30° increments or can be locked out and free float for easy access. The mounting rails are 6061 aluminum and have a Mil-Spec picatinny profile providing a extremely secure mount. All metal, CNC machined components (except over-mold) for strength and durability.
