A matched arrow set including a first arrow and a second arrow. The first arrow including: a first shaft, a first bushing coupled to the first shaft, and a first nock received in the first bushing. The second arrow including: a second shaft, a second bushing coupled to the second shaft, and a second nock received in the second bushing. The first shaft and the first bushing define a first weight, the second shaft and the second bushing define a second weight greater than the first weight, and a first arrow weight is substantially the same as a second arrow weight.

High impact strength lighted nock assembly

A cocking system for retracting a string carrier on a crossbow that is substantially silent during operation. The cocking system includes a string carrier with a catch that is moveable between a closed position that engages a draw string, and an open position that releases the draw string. The string carrier slides along a center rail between a released configuration and a retracted position that locates the draw string in a drawn configuration. A trigger is positioned to move the catch from the closed position to the open position to fire the crossbow when the string carrier is in the retracted position. The cocking system includes a retaining mechanism that retains the string carrier in the retracted position while permitting a draw string to disengage and fire an arrow.
