Trigger Pull: The trigger pull on the Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun is single action only since the right side charging handle must be cocked first before you can shoot it to engage the action. The trigger is short and fairly light but not overly light. The real fun happens with the Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun when you switch it over to full auto mode and with just one pull and hold of the trigger you empty the 25 round magazine in a mere matter of seconds at 1400 rounds per minute.
Accuracy: I have not actually shot this BB Rifle to date but expect it to get similar results to the other Crosman Full Auto BB Machine guns I have already reviewed. I am expecting a bit more velocity with the longer barrel extension installed and would be happy if I was able to get in the mid 400’s. Accuracy should also be about the same with 1 inch semi auto groups from 30 feet out expending a bit when in full auto.
Build Quality: The Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun is well made all around. Weighing in at 6.07 pounds without any add on accessories other than the included compact Red Dot sight. It feels solid and well built. There is a lot of metal going on inside and out of this rifle but keep in mind the top and bottom receiver are plastic with metal parts where they need to be like in the internals, pretty much all the working parts are metal, the magazine is full metal, the buffer tub is metal, charging handle, selector switch, magazine release, bolt release, trigger and of course the barrel is metal.
Realism: The Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun is not modeled after any real steel gun I know of. It resembles a futuristic weapon you would see in a SciFi Action Movie or Alien First Person Shooter. I was not a fan of it when it was first released by Crosman but after seeing and holding it in person it is growing on me quickly.
Pros:
Very unique, not like your regular Replica Rifles, very futuristic in design.
Drop out magazine doubles as the 300 round hopper and holds CO2 and BB’s.
Comes with Red Dot Sight and lots of rails for mounting what every you want on it.
Can be either a Pistol or Rifle or a PDW by adding or removing the Barrel Extension and Rear Stock.
Barrel Extension actual lengthens the barrel and should increase fps, not just for show!
Tactile comfortable rubber padding in multiple locations.
Semi auto and full Auto selectable.
Expected higher fps of up to 480.
Cons:
Some people may not like the look? Not like your normal modern rifle.
Front rubber grip comes off really easy at least on mine?
Will require barrel extension for full velocity.
Comments:
The Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun is a brave move by Crosman, I was not expecting something like this from them and when I originally saw it I was not sure if it was a good idea or not but again once seeing it in person and actually holing it I feel a lot better about it. It will for sure appeal to those looking for a futuristic Airgun or wanting something that looks like a gun from a video game or SciFi movie. I also like the versatility you have with the Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun being able to configure it how you like either as a Pistol, full on Rifle or PDW style shooter.
