The Carbon Express D-Stroyer is a dual-spine-weight-forward shaft with a.244-inch inside diameter and the patented two-spine construction that reduces oscillation, so it takes a CX Launchpad.244 nock.
It is offered in three spines, 350 at 8.9, 400 at 7.9 and 500 at 7.0 grains per inch, sorted to +/-.003-inch straightness.
It uses a spine-specific CX insert and takes a 19/64 field point rather than the micro 8-32, so match the point and insert to the shaft.
