The X-BOW FMA bolts are made of 100% carbon and are ideally suited for the X-BOW FMA Cobra R9 System, Cobra R10 and Cobra Adder. The three variants Standard, High Range, and Deep Penetration are designed for different requirements and purposes. The High Range version is suitable for longer distances and has a 50-grain tip, which makes the bolt a little lighter and lets it fly further. The Deep Penetration version with a 125-grain tip is designed for more effective shooting with maximum impact on the target because the heavy tip shortens the distance but allows the bolt to penetrate deeper into the target. Finally, the standard bolt is the optimal combination of distance and effect.
In the HD version, the bolts have been improved once again and are equipped with an aluminum moon nock. This nock, milled from one piece, is much more stable than nock made of plastic and therefore much more durable.
