Pine Ridge Nitro Speed Bomb Brown 2 pk.

You can eliminate three typical brass nocks and the effort to crimp and burn the shrink tubing, while retaining the ability to adjust them to the perfect position on the string. A brass nock is pretty much stuck where you crimp it while the Nitro Speed Bomb can be tweaked on the string after multiple shots to find the sweet spot. However, once achieved, they stay where you want them, thanks to their durable and tacky material. No need for shrink tubing, crimps or serving. Once set, just shoot!
