Firenock D+ style lighted nock is designed to work with 500fps crossbows that have to work with clip-on style nocks. Firenock D+ style is to fit a crossbow arrow with an Internal Diameter of 0.300" and string serving of 0.165" OD without the presence of a bushing that would change the ID of the shaft, i.e., one must remove the bushing on the Ravin Arrow before it can be correctly installed. Please discuss the ramifications with your bow shop or custom string maker. Aerobolt III is advised to be used as the projectile shaft due to the extreme pressure asserted by a 500 fps crossbow.

Based on its polycarbonate namesake but made for extra durability, the Firenock D+ Replacement Nocks take advantage of our patented Square in a Circle Technology for concentricity. They are made of 6061 Aluminum and anodized with a beautiful orange or green color. Instead of utilizing the Compression System for a secure fit, a machined open slot allows circuit installation.
