The Speed-Nok features a peep aligning tail while maintaining the weight of 1 brass nock. Machined from aircraft aluminum to maintain the strength to securely fasten to the bowstring and eliminate the common slipping of the brass nock. The tail maintains the peep rotation alignment and a no-bite rocker radius was added to the design to eliminate arrow nock pinch at full draw. Speed will increase up to 15 feet per second through the elimination of more than one nock set and the rubber band peep aligners. The Speed-Nok also may be quickly and easily adjusted for rotation or location using a #0-point phillips screwdriver.
