New Crosman ST-1 Full Auto BB Gun Announced

The new Crosman ST-1 full auto BB gun is a new announcement from Velocity Outdoor. The company highlights the product as being perfect for serious plinking, maximum fun and “alien defense training”.

The HAM Team has not encountered many needs yet for alien defense training, but it certainly sounds as if the ST-1 will be another great tool for culling those feral soda cans that we find lurking about the place!

What’s for sure is that this is a modular, customizable airgun that can be operated in a variety of different ways.


In fact, the Crosman ST-1 is a selective fire BB gun. The options are semi-and fully-automatic fire. It’s also configurable as a pistol and as a long gun (strictly we can’t call it a rifle as it has a smooth bore barrel).


The ST-1 has a basic 6.125 Inch barrel. This can be lengthened using a barrel extender. In this case, the barrel length becomes 17.75 Inches. Crosman gives a maximum Muzzle Velocity of 450 FPS – presumably with the barrel extender in place.

The buttstock has two positions. Alternatively it can be removed altogether for use in pistol configuration. This reduces the overall length to 17.75 Inches, down from 33 Inches for the barrel extender plus stock length.


The drop-free magazine contains the two 12 Gram CO2 cartridges. It has a 25-shot capacity. However, there’s also a high-capacity, 300 round reservoir built-in, together with a speed loader. This is another unusual feature that will help to reduce the frustrating downtime spent loading BBs.

In use, the magazine is installed in a substantial forward hand grip with textured surfaces.


Supplied with a red dot sight, the Crosman ST-1 is equipped with top, side and bottom Picatinny rails for adding accessories.

Pyramyd Air is showing an in-stock date of 31 August 2022. The price is $279.99 for what is – in effect – three guns in one!
