Lancaster Archery Supply TechXPert Randy Groff reviews the Gold Tip GTO Nock. This is a new arrow nock introduced by Gold Tip in 2015. Using the appropriate bushing, the GTO nock can be used in just about any Gold Tip arrow.

Groff points out that the GTO nock is short, so it doesn't flex, and its throat is rounded, which enables the string to oscillate when the nock is attached. Allowing the string to oscillate aids in arrow flight, and helps to mask imperfections in shooting form.
