Custom U+ Style Firenock Lighted Nock System (3) for Ravin 500

Firenock U+ style lighted nock is designed to work with Ravin 500fps crossbows that have to work with clip-on style nocks.  Firenock U+ style is to fit a crossbow arrow with an Internal Diameter of 0.300" and string serving of 0.133" 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. It is known that some Ravin 500 fps crossbows have string serving OD size that is smaller than 0.133", which U+ style nock will not fit well. While some older ravin string serving is at 0.127", which a "C+" nock is what you should be using instead. Please discuss the ramifications with your bow shop or custom string maker. It is advised to use Aerobolt III as the projectile shaft due to the extreme pressure that is asserted by a 500 fps crossbow.

Based on its polycarbonate namesake but made for extra durability, the Firenock U+ 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 for circuit installation.
