The Break Gunner (ブレイクガンナー) is the device used by Chase to transform into the Kamen Rider-like warrior, Mashin Chaser. It also doubles as his main weapon of choice.

Functionality
To transform, the user firmly holds the Hard Gear Grip (ハード ギア グリップ) and slams their hand on the Destruction Muzzle (ディストラクション マズル) spring-like button, holds it for a few seconds, then lets go and aims the Break Gunner above their head, causing the device to announce "Break Up" (ブレイクアップ) while a series of shadow tires and electricity projects out of it to surround the user, combine into user's body, thus ending the transformation sequence into Mashin Chaser.

By pressing and releasing the Destruction Muzzle, Mashin Chaser can also activate the Break Gunner's Gun Mode. Pressing the Destruction Muzzle once again activates its Break Mode as well.

Since the Break Gunner was based on Proto-Drive, the user can "Tune" up using either Shift Car or Viral Core powers by inserting them into the slot behind the purple spoiler. Using a Shift Car will simply add its power to the Break Gunner, while using a Viral Core will allow Chaser to use the appropriate Busou form. Inserting a Viral Core into the Break Gunner and pushing the Destruction Muzzle once more will activate its finisher.

Other Version

 * Kamen Rider Lupin uses a gold-colored version of the Break Gunner called the Lupin Gunner (ルパンガンナー) as his transformation device, which has an additional Blade Mode (ブレードモード) that is accessed via the Lupin Blade Viral Core.
