Designed in response to customers heading to combat zones, the Quad magazine carrier also works very well for those who must be discreetly yet heavily armed. It holds four magazines in horizontal position, while tension units and straps secure the magazines. Galco International invented the modular interchangeable component shoulder systems (originally known as the "Jackass Rig ") in 1969. Today, Galco continues to offer quality and versatility by developing products that enable you to design the perfect system to suit your needs. For example, you may assemble a two-handgun rig, a half harness system, or add tie downs and cuff case to an existing system. The possibilities are endless. The QCL is ambidextrous and available in tan or black finish.
