Overview of the UK/US Gun Reform

US gun laws are brought inline with UK gun laws (self defense using guns is illegal)

Only olympic/sport shooting with licenses is legal

Non-automatic break/bolt/lever action centerfire rifles are legal

Non-automatic straight pull centerfire rifles are legal

Pump action rimfire rifles in 0.22 inch caliber only are legal

Semi-automatic rimfire rifles in 0.22 inch caliber only are legal

US shotguns in maximum 3 shells including chamber are legal (UK shotguns in more than 3 shells on a rifle license are legal)

Rest of guns are illegal including all UK/US handguns after the banning of hunting

UK/US gun licenses are not blanket licenses (open/concealed carry of guns is illegal)

US gun licenses are simplified into an age 18 long gun license or a prohibited gun license for maritime and museums

While the UK long gun licenses are not simplified in the reform, the age requirements are to prepare for the U.S.E. under DC law

Borrowing rifles/shotguns with supervision is raised to age 16 (UK age to borrow a rifle is adjusted to age 16)

Borrowing airguns with supervision is raised to age 14

Raising the ages for most gun requirements but lowering the age for the supervision of guns to age 18 (to satisfy the American NRA and the future U.S.E.)

US minimum long gun lengths adjusted to a 12 inch barrel and 24 inch overall length for rifles, and a 24 inch barrel and 40 inch overall length for shotguns

UK/US age for the supervision of guns is lowered to age 18, UK age to borrow a rifle is lowered to age 16, the rest of the UK/US gun ages are raised or unchanged

In layman's terms it's Scottish NRA standards for the American NRA (and UK gun laws mirroring the new US gun laws)
