Helix airsoft brings the only Vector-compatible RIS system to the airsoft market. Using lightweight machined aluminum for superior durability and performance, this incredibly high-quality rail system allows for maximum customization of the airsoft Kriss Vector. Replacing the small rail sections that come stock on the Vector rifle, this rail system adds a whopping 12" of picatinny/weaver rails for attaching any aftermarket accessories such as lights, lasers, grips, and more. No matter what accessories the mission requires, the Vector with the Helix Axem rail system can hold them all. The interior of the Axem KV RIS also accommodates many center-bore mock suppressors, including the Helix Trident suppressors. Lastly, the Axem KV rail kit includes a CNC aluminum KV charging handle with a thin red line accent to replace the stock polymer parts. If it's time to upgrade one of the hottest airsoft rifles on the market right now, the Helix Axem KV is the biggest and best upgrade available!
