"Knight Rider" APS GBU Custom - Gel Blaster (Metal)The Knight Rider custom is the APS MPX but with the extras to make you stand out from the crowd. Packed with plenty of punch and all the looks this blaster is great for the new, experienced and the pros. The gear box has had work done running a super fast 13: 1 SHS gear ratio and pumping up to 310 FPS. If you want to take this bad boy further, a Leviathan Mosfet would be the next upgrade.
