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: Staring with the velocity test we did use brand new CO2 for this and the temperature was around 20 degrees Celsius or 68 Fahrenheit so not too cold or warm. With the Barrel extension installed we managed to average 418 fps shooting 4 rounds. With the barrel extension removed as expected the velocity did drop a bit down to 373 fps shooting 4 rounds and averaged out.

For our Accuracy Test we placed the Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun in semi auto for the first portion and fired 10 shots into the paper target setup 30 feet away, we were using a semi rested shooting position with a sand bag up front to rest the gun on and me sitting on a stool in the back. We did not sight the red dot in and found that out of the box the Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun shot down and too the right a fair amount but at least we were able to get most of the shots on the paper target and on camera. The grouping was around 2.5 to 3 inches so not super great but not bad either. We then flicked the main selector to Full Auto since this is what most people want to see. We also reloaded the magazine with 25 rounds from the onboard hopper and unloaded the full magazine in a second or two. We did aim a bit higher and to the left this time to get the shots closer to the bullseye and we were able to do so with most of the 25 shots all within about 2.5 to 3 inches so not really any difference shooting in semi or full auto at least in terms of accuracy.

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 we know of. It resembles a futuristic weapon you would see in a SciFi Action Movie or Alien First Person Shooter. We were not a fan of it when it was first released by Crosman but after seeing and holding it in person it is growing on us 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.
