According to CNN this is a accessory to a firearm, but I don’t know how. Anyways all I’ve done is function tested it, i have two of these. the backpack itself wasn’t ever used. But reguardless this thing is pretty sweet. Cool 4th if July toy, or for lighting lots of things 25 feet in front if you on fire at once. The backpack is 3.3 gallons and makes it to around 4-5 minutes if continuous flame. You can mix diesel and gas too if you’d like lol. Lmk if you have any questions. In before “ i wOuLd nEvR bUY a UsED fLAMe THrOwER”. This company has amazing customer support. My other one I’ve used pretty extensive on land for controlled burns amongst other stuff. Works like a charm
