Crosman More from the manufacturer


US manufacturer Crosman introduces a fully automatic CO2 airgun inspired by the futuristic KRISS Vector carbine. Its synthetic frame in white finish in combination with black parts offers a very distinctive and unique look.

The collapsible buttstock with a rubber buttpad is removable and the same goes for the sound moderator which mostly functions as a barrel extension. You can turn this compact carbine into a pistol in no time. The smoothbore barrel is made of steel and has a length of 155 mm. Its length can be extended to 394 mm with the sound moderator attached.

The airgun is powered by two 12g CO2 cartridges which must be inserted into the massive magazine with a reservoir for more than 300 steel BBs in .177 caliber (4,5 mm). You have to pull out the rod on the lower side of the magazine, turn it upside down and shake it a little in order to load 25 shots into the mag. All you need to do then is to push the rod back and you are good to go. It is also possible to load the magazine without taking it out of the gun.

Crosman ST1 shoots in both semi-automatic and full-auto fire modes. You can switch between them with a selector switch which also functions as a safety. The fire selector is ambidextrous and is located above the pistol grip. The shooting experience is further enhanced by the addition of the Blowback system which simulates the realistic movement of the bolt after each shot.

The forearm is outfitted with Picatinny rails for additional tactical accessories. You can mount the included red dot sight or any other scope on the top rail.
