|The four Kôsenjû guns and rifles|
In the image above, we see from top to bottom: Kôsenjû SP Rifle (光線銃SP ライフル, 1970), Kôsenjû SP Gun (光線銃SP ガン, 1970), Kôsenjû 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 Kôsenjû Custom Gun (光線銃 カスタム ガン, 1976).
The Kôsenjû SP and Kôsenjû 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 Kôsenjû Custom Gun is more focused and stronger than that of the Kôsenjû SP Gun, which improves the range of the gun.
The Kôsenjû SP Gun has a white handle and a metal trigger and hammer.

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

The two rifles are quite different. The Kôsenjû SP Rifle is smaller and much lighter than the Kôsenjû Custom Lever Action Rifle. It is a real toy rifle, and also a lot cheaper than the Kôsenjû Custom Lever Action Rifle. The Kôsenjû Custom Lever Action Rifle on the other hand, is very close to a real riffle. Like the Kôsenjû Custom Gun, it has a better light source and greater range.
The Kôsenjû 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 Kôsenjû 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 Kôsenjû targets.
|Leaflet included with Custom Gunman/Lion explains you cannot use SP Gun and Riffle|
In particular, the Kôsenjû 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.
|Kôsenjû Custom Target with focus lens attached to the sensor in the middle|
The Kôsenjû SP Gun and Rifle can be used for the 1971 Kôsenjû Custom Target, if the focus lens which came with the target is attached to its light sensor. The tag attached to the Kôsenjû Custom Target shows its backward compatibility with the Kôsenjû SP series.
|The Kôsenjû 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.
