The minimum legal rifle barrel length in the United States is 16 inches, as defined by the National Firearms Act (NFA). Barrels shorter than this are classified as short-barreled rifles (SBRs), which require registration and a tax stamp. Different countries may have varying regulations regarding minimum barrel lengths. Always check local laws to ensure compliance.
As far as largest handgun cartridge goes, it would be the Pfeifer Zeliska .600 Nitro Express. If you're referring just to size of the firearm itself, that can be a bit ambiguous. Take, for example, the AK style "pistols" manufactured which are classed as pistols simply because they lack a buttstock (otherwise, they'd have to be NFA regulated SBRs, having a barrel length of under 16 inches).
The term ''short-barreled rifle'' means a rifle having one or more barrels less than sixteen inches in length and any weapon made from a rifle (whether by alteration, modification, or otherwise) if such weapon, as modified, has an overall length of less than twenty-six inches. Federal FIrearms Act regulations prohibit any long-barreled firearm from having a barrel shorter than SIXTEEN inches.
Making a friend is just like any other site. Like everyone's parents told you... Don't trust anyone. You can just chat with people. Beware, you make enemies by sending random SBRs and chatting randomly to the older, cool, and experienced players. It's okay though, they just don't put up with randoms. They made friends somehow though.. Didn't they? Send someone a line about training, votes, or just say how cool their page is! Make it a combersation, get into some fun talk, and then send a SBR. Just remember, don't go Hi wanna be friends? That's creepy.. Get to talk first. Never trust anyone and give real info, they could be fakers.
