SGM Tactical SSGMTRPR: SGM Tactical is a company that wanted to build a gun mag like no other. It was their intention to create mags that would feed flawlessly but at the same time give outstanding performance and longevity. They then used that same technology they used in mags to make other firearm parts more useful. This rail, for instance, provides a stable platform for you to use rail-mounted optics. Constructed of Dupont and polymer, this rail is extremely durable and will hold up to hard use while providing a rock-solid mounting point for your optic to hold zero. This rail will work with Saiga patterned AKs as well as other fixed stock Russian patterned AKs.
