Crosman ST1 Full Auto: Straight from outer space...

This is the Crosman ST1 Full Auto CO2 pistol/carbine. Although it has a very futuristic look, its design was inspired by the real KRISS Vector. The Vector was developed by the American company KRISS in early 2007. The word "kris" with one "s" also means a dagger with a curled blade, originating from the island of Java.

The weapon has since been modified into numerous versions. However, the foundation is still a special locked bolt mechanism that allows the bolt mass to move back and down, which has a positive effect on the stability of the weapon when firing. Therefore, there is room behind the magazine well for this system. The Vector is produced for the armed forces as an automatic, and for the civilian market as a self-loading weapon. The original prototype had a cadence of 1,500 rounds per minute, later reduced to 1,200 rounds per minute.

The spectrum of calibers is very broad. From .22 LR to .357 SIG, .40 S&W, 9mm Para, 9x21mm, to 10mm Auto. Standard or extended GLOCK magazines can be used depending on the caliber. The gun also comes in many color variations.

The magazine housing with check holes is made of black plastic, the mechanism and valve of non-magnetic metal. Above the trigger and on the right side of the gun body there is a button which enables you to remove this whole block from the gun. The button on the other side is secured in the body by a longitudinal plate with the serial number printed on it. Above the pistol grip is the lever of the ambidextrous three-position safety, the edge positions of which are marked by raised bump stops. The forward-facing safety position secures the weapon, the upright position allows single shots to be fired, and the rearward-facing position allows burst firing. Behind the pistol grip is a sliding pin that holds the extended neck of the shoulder rest with a spring-loaded locking button on the weapon. 

A 22mm Picatinny rail for mounting accessories is molded on the top and bottom of the gun. Others can be mounted on the two black side rails that are screwed onto the gun's frame. In this basic configuration, without the stock and "silencer" extension, the gun is already shootable as a chunky pistol. All it needs is a red dot sight or sighting optic.

CARBINE MODIFICATION

This can be done in seconds. First, attach the shoulder rest carrier to the extended metal cover of the mechanism. Then slide it on and lock it in one of the two positions with the spring-loaded button. The difference between the short and longer backrest is 55mm. Slide the moderator onto the barrel shroud with the inscription facing upwards. Turning it to the right will automatically lock the spring-loaded pin. To remove it, we must pull back the small knob above the muzzle.

As already mentioned, the body of the gun is moulded from white plastic. All controls are black, as are the softened and roughened grip surfaces on the pistol grip, "magazine" well and shoulder rest. The type of weapon, calibre, country of origin and necessary safety notices are printed on the left side. The entire weapon is stored in a sturdy paper mache bedding when partially disassembled. The shoulder rest, red dot sight with a battery, appropriate Allen wrenches, the "magazine" and the sound moderator are separately placed. In the imprinted box we can also find the manual.

SHOOTING

Insert the magazine into the secured weapon, use the safety to select the firing mode and pull the slide rearward. The trigger is quite stiff, which is normal for a "military" weapon.

We can shoot without a shoulder rest, but it is more comfortable to shoot with it. You can also shoot at paper targets with circles, but shooting at plinking targets up to 10-12m is much more fun.

When firing single shots, it is possible to hit a beer can with every shot at this distance with a properly adjusted red dot sight. When fired in bursts, it's not so easy. Adding to the shooting experience is the fact that the Crosman ST1 is equipped with a very realistic Blowback system. After firing 25 rounds, we put the gun on safe, pull the magazine catch up again, turn the whole gun magazine up and feed more ammunition from the reservoir. In colder weather, it was possible to fire 120 rounds per charge (two CO2 bombs). Then the pressure was no longer able to cock the "slide". Presumably, in warmer weather, the number of shots would be higher…

The use of a moderator has no effect on accuracy or noise. But it does make the gun look more impressive. Even if it is a "pellet gun", it is necessary to adhere to the principles of gun safety when shooting. Even a 3J BB at 131 m/sec can do serious damage.

in conclusion

What to say about the gun in conclusion? It will definitely cater to those who prefer a futuristic look and prefer plinking shooting. And the shooter who prefers precision or longer range shooting will find a rifle or pistol to his liking from the wide range offered by Balistas.
