According to Forbes, Cargill's store is "the first legal Bitcoin-friendly firearm retail business in the country, if not the world." He started "accepting Bitcoin as an alternative to dollars for all sales... in January" and he was "inundated with [so many] emails and phone calls" that he began selling online as well. 

Ironically, Cargill says he "never wanted to sell guns online," but the demand for them required it.

Like all other gun dealers, firearms purchased online from Central Texas Gun Works are shipped to a Federal Firearms Licensee (FFL) near the buyer. The FFL then conducts a background check before releasing the firearm to the would-be purchaser.
