silly shell variant capable of fitting six 13x70mm or twelve 13x35mm darts. there's also text engravings on them detailing the shell specs and SYS for its designer (systemphantom)

it will require some practice to get the darts inside, as it is a very tight fit and you must make sure each dart stays in its own channel and doesn't get squished into a neighbouring one. also the performance is obviously going to be pretty terrible but who cares when you're shoving twelve whole darts into the form factor of a regular 34x80 silly shell. Given the sheer volume of foam you have to displace i'd be surprised if this works out of anything less than a breacher or battle axe
