It will for sure appeal to those looking for a futuristic Airgun or wanting something that looks like a gun form 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.
