The VFC Saber M-Lok Line is the first choice rail for your VFC M4 platform from Elite Force. Constructed out of aluminum for durability without increasing the overall weight. This M-Lok Rail is much lighter compared to other aftermarket rail systems on the market, and the durability is top tier. The finish is anodized matte black to protect the rail system from rust and light scratches depending on the environment. This is designed to work with TM compatible variant airsoft guns.
