|The four Kousenjuu guns and rifles|
In the image above, we see from top to bottom: Kousenjuu SP Rifle (光線銃SP ライフル, 1970), Kousenjuu SP Gun (光線銃SP ガン, 1970), Kousenjuu Custom Action Lever Rifle (光線銃 カスタム レバーアクション ライフル, 1971) and Kousenjuu Custom Gun (光線銃 カスタム ガン, 1976).
The Kousenjuu SP and Kousenjuu Custom guns are similar in size and design. The main exterior differences are the color of the handle and the trigger mechanism. Furthermore, the light source of the Kousenjuu Custom Gun is more focused and stronger than that of the Kousenjuu SP Gun, which improves the range of the gun.
The Kousenjuu SP Gun has a white handle and a metal trigger and hammer.

The Kousenjuu Custom Gun has a brown handle and a plastic trigger and hammer.

The two rifles are quite different. The Kousenjuu SP Rifle is smaller and much lighter than the Kousenjuu Custom Lever Action Rifle. It is a real toy rifle, and also a lot cheaper than the Kousenjuu Custom Lever Action Rifle. The Kousenjuu Custom Lever Action Rifle on the other hand, is very close to a real riffle. Like the Kousenjuu Custom Gun, it has a better light source and greater range.
The Kousenjuu SP Rifle is prepared for firing by pumping the handle bar underneath the barrel. It came with a small toy telescope sight, with plastic lenses.

The Kousenjuu Custom Lever Action Rifle is loaded by moving the lever underneath the trigger. A professional telescope sight (Custom Lever Action Rifle Scope) with real glass lenses was available as an accessory.

Because of the different light sources in these guns and rifles, they are not fully compatible with all available Kousenjuu targets.
|Leaflet included with Custom Gunman/Lion explains you cannot use SP Gun and Riffle|
In particular, the Kousenjuu SP Gun and Rifle cannot be used with Custom Gunman and Custom Lion, as explained by the leaflet pictured above. The leaflet explains that for these targets the Custom (Lever Action) Rifle or Custom Gun should be used. Interestingly, the price for the rifle is quoted as ¥5,000 in 1976, significantly lower than the 1971 introduction price of ¥14,000.
|Compatibility diagram included in the Custom Gunman manual|
The compatibility diagram pictured in the Custom Gunman manual also shows which rifle and gun can be used with which target.

The Kousenjuu SP Gun and Rifle can be used for the 1971 Kousenjuu Custom Target, if the focus lens which came with the target is attached to its light sensor. The tag attached to the Kousenjuu Custom Target shows its backward compatibility with the Kousenjuu SP series.
|The Kousenjuu Custom Target also sports the SP label|
This compatibility stuff may sound more complicated than it actually is. Just take a look at the table presented below, which summarizes it all.
