ChronoBarrel

The ChronoBarrel is a Nerf barrel extension that was released in fall of 2018 under the Ghost Ops sub-series. It requires two "AA" batteries to be operated.

It comes packaged with six Elite Darts and instructions.

Details
The ChronoBarrel is a detachable barrel extension that can track darts as they are fired from the blaster it is attached to. This can be used to track remaining ammunition in the blaster or the speed at which darts are fired, both of which are read out on an LCD screen. Tracking remaining ammo is done by first setting the number of darts loaded with the use of the accessory's buttons. Fired darts, when their speed is tracked, are read out in either feet per second (FPS) or meters per second (m/s).

There is a single tactical rail underneath the ChronoBarrel.

History
The ChronoBarrel was first announced at the 2018 Toy Fair.

Trivia

 * Only darts shot at certain speeds will trigger the counter and chronograph. If a dart is shot too slowly or is manually pushed/dropped through the ChronoBarrel, it won't be counted.
 * When using half-length darts, such as Stefans, the chronograph function is unreliable. As it uses the length of Elite Darts as a standard to determine how fast the darts are going, the shown result will be roughly double of the real one.
 * The plastic that is used in it is noticeably clearer than what was used for other translucent products, such as the Clear Series blasters.
 * A clip can be stored on the barrel by the section just above the tactical rail.
 * The barrel bears resemblance to the Recon MKII barrel extension, albeit with additional electronic components. Similarities include their comparable form factor, the presence of a tactical rail on the bottom, and a front iron sight, although the ChronoBarrel's sight has a thinner post and features a screen behind it.
