This upgrade makes Beyblade Burst Superking and Dynamite Battle launchers capable of accepting clip-on prongs for multiple generations of Beyblade.
Large Size:
By replacing the standard prongs on the Superking or Dynamite Battle launchers with the large size option of this upgrade, the launcher becomes compatible with the detachable Metal Fight Beyblade (MFB) prongs that come with that generation's Light Launcher LR, Digital Power Launcher, and Rip-Guage Launcher.
The screws and springs necessary to assemble this upgrade can be purchased here:

Small Size:
If you already own or intend to purchase one of the previously listed MFB launchers that uses or comes with this style of clip-on prongs, then you only need to purchase the small size option for this upgrade since it can be combined with the clip-on mechanism from any of these MFB launchers as shown in the small size's product photos.
Some disassembly and reassembly are required for this upgrade to be used. MFB-compatible clip-on prongs can only be acquired from the three previously mentioned MFB launchers: the Light Launcher LR, Digital Power Launcher, and Rip-Guage Launcher.
Clip-on launcher prongs for Beyblade X, Burst, and G1 that are compatible with this upgrade and the original clip-on style MFB launchers can be purchased through the following links:
