In a world of unintended consequences, it was only a matter of time before someone started a crowdfunding portal for the shooting sports.
FireFunder is a crowdfunding website that supports campaigns to raise money for gun accessories, bags & apparel, blades & tools, lighting & optics and camping & outdoors.
Huntego is now running a campaign to raise funds for its CleanShot, a gun bore cleaner where you merely shoot a specially formulated shotgun shell at any range and, wham!, you gun is cleaned.
This is a typical pre-sale campaign where your money buys the product.
