Is the Nerf velcro dart same as dart tag darts?

There are four basic types of Nerf darts:

Clip System

Whistler

Suction

Tagger

Clip system darts (once called 'streamlined') are made to fit into any ammo clip for nerf blasters (longshot, longstrike, recon, alphatrooper, rayven). They are loaded into a clip or drum, which is inserted into the gun.

A gun that uses a revolver-style or open drum will most likely use Whistler or Tagger darts (tagger darts have velcro for use with Nerf's Dart Tag vests). These include: Barricade, Maverick, Specter, or any of the dart tag line. Tagger/Whistler/Suction are generally interchangeable.
