Photo Anson & Deeley Action - A type of boxlock action design for a break-open gun, patented in 1875, the essence of simplicity utilizing only two springs and three moving parts (per barrel).

One of the most successful action designs ever, and still produced to this day by innumerable makers in many countries. any replica of any firearm described in subparagraph (A) if such replica (i) is not designed or redesigned for using rimfire or conventional centerfire fixed ammunition, or (ii) uses rimfire or conventional centerfire fixed ammunition which is no longer manufactured in the United States and which is not readily available in the ordinary channels of commercial trade.

Any weapon used in an attack: 18th century boarding pikes, Civil War Springfield muskets, World War II Garands, Vietnam M-16s are all assault weapons.

Autoloading [Action] - A type of firearm which, utilizing some of the recoil or some of the expanding-gas energy from the firing cartridge, cycles the action to eject the spent shell, to chamber a fresh one from a magazine, and to cock the mainspring in preparation for firing with a manual pull of the trigger. Photo Automatic [Action] - A type of firearm which, utilizing some of the recoil or some of the expanding-gas energy from the firing cartridge, cycles the action to eject the spent shell, to chamber a fresh one from a magazine, to cock the mainspring and to fire again.

ADL, BDL - Suffix designations used by Remington to signify grades of various models of bolt action rifles. The BDL version generally adds a hinged floorplate, slightly better wood, checkering, contrasting forend tip and pistol grip cap.

ADL and BDL stand for A Grade De Luxe and B Grade De Luxe.

Ballistics can be categorized into three phases: Interior (the projectile's behavior inside the bore), Exterior (the projectile's behavior in flight), and Terminal (the projectile's behavior upon contact with the target).

Banknote Engraving - See Bulino Bar - The portion of a break-open gun's action extending forward from the bottom of the standing breech, supporting the hingepin.

We try to describe the percentage of finish neither optimistically nor conservatively but exactly as it is.Photo Aperture Sight - See Peep Sight APUN - Action Patent Use Number.Under patent law during the period of greatest creativity in the British firearms trade (circa 1860 - 1910) gunmakers typically numbered each patented component with its own number of use of the patent (not the number of the patent itself as registered with the patent office as in the USA)---irrespective of the serial number of the firearm.Photo Ball Screw - See Worm Ball & Shot Gun - A firearm, built to be able to shoot either a single projectile or a load of shot pellets; generally built heavier than their shotgun counterparts and fitted with rudimentary rifle sights; often either with robust rifling just at the muzzle or with Lancaster Oval Boring.See Paradox Ballistics - The study of the action of propellant powders upon projectiles, their speeds, energies and trajectories.

Under patent law during the period of greatest creativity in the British firearms trade (circa 1860 - 1910) gunmakers typically numbered each patented component with its own number of use of the patent (not the number of the patent itself as registered with the patent office as in the USA)---irrespective of the serial number of the firearm.

Photo Backboring - Enlarging the internal diameter of a shotgun barrel beyond its proper standard (.729" in 12 gauge) by reaming, in an effort to reduce the recoil or to improve the shot pattern.
