19 Other Firearms Definitions You Need To KnowPoint Blank RangeThe farthest distance that a target of a given size can be hit without holding over or under with the sights. The exact range is determined by the performance of the cartridge used, the ZERO range, and the accepted size of the target area. This term is not to be confused with point blank shooting. CockedA state of readiness of a firearm. The hammer (or similar mechanism if there is no hammer) only needs to be released by the trigger to cause the gun to fire. Damascus BarrelsBarrel tubes built up by twisting alternate strips of iron and steel around a fixed rod (mandrel) and forge-welding them together in varying combinations according to the intended quality and the skill of the maker. The rod was withdrawn, the interior reamed and the exterior filed until the finished tube was achieved. Damascus barrels may be recognized by any of a variety of twist or spiral patterns visible in the surface of the steel. Before the 20th century, barrels were typically built in this manner because gunmakers did not have the technology to drill a deep hole the full length of a bar of steel without coming out the side. Percussion CapA small metal explosive-filled cup which is placed over the nipple of a percussion firearm. As the cap is struck by the hammer, it explodes and sends a flame through the flashhole in the nipple to the main powder charge. GunpowderAlso called black powder, gunpowder is a mixture of sulfur, charcoal, and potassium nitrate. It burns rapidly, producing a volume of hot gas made up of carbon dioxide, water, and nitrogen, and a solid residue of potassium sulfide. Because of its burning properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms and as a pyrotechnic composition in fireworks. The term gunpowder also refers broadly to any propellant powder. Modern firearms do not use the traditional gunpowder (black powder) described here, but instead use smokeless powder. Hang FireAn unexpected delay between the triggering of a firearm and the ignition of the propellant. This failure was common in firearm actions that relied on open primer pans, due to the poor or inconsistent quality of the powder. Modern weapons are susceptible, particularly if the ammunition has been stored in an environment outside of the design specifications. Reloaded ammunition may also be the cause if not reloaded properly MusketoonA musket shortened for cavalry use. PinfireAn early form of complete, self-contained cartridge. It included bullet, powder and ignition primer, all in one package. The primer was located towards the base of the cartridge, but completely internally. The pin, shaped like a little finishing nail, pointed on the inside end and resting on the internal primer, projected radially about a quarter-inch to the outside of the base of the cartridge. When loaded, a pinfire gun showed the tips of the pins exposed through small slots in the tops of the breech faces of the barrels. To fire, hammers fell on the pins, driving them (through the wall of the cartridge) into the internal primer. Improvised FirearmA firearm manufactured by someone who is not a regular maker of firearms. Saturday Night SpecialA slang term for a small inexpensive handgun. Saturday night specials have been defined as compact, inexpensive, small-caliber handguns with perceived low quality; however, there is no official definition of "Saturday night special" under federal law, though some states define "Saturday night specials" or "junk guns" by means of composition or materials strength. Low cost and high availability make these weapons attractive to many buyers despite their shortcomings. JewelingA cosmetic process to enhance the looks of firearm parts, such as the bolt. The look is created with an abrasive brush and compound that roughs the surface of the metal in a circular pattern. Wheel-LockAn early firearm mechanism in which a wheel with serrated edges is wound against the tension of a strong spring and spins against a piece of iron pyrite, sending a shower of sparks into the pan to ignite the charge. ChamberThe rear portion of the barrel or firing cylinder in which the cartridge is inserted prior to being fired. Rifles and pistols generally have a single chamber in their barrels, while revolvers have multiple chambers in their cylinders and no chamber in their barrel. Federal Assault Weapons BanPart of the Violent Crime Control and Law Enforcement Act of 1994.
It produced a 10-year federal ban on the manufacture of new semi-automatic assault weapons with certian specifications.
Firearms with specific features were defined as assault rifles.
Including the AR-15, certain versions of the AK-47, the TEC-9, the MAC-10 and the Uzi,
several of which had become the preferred weapon of violent drug gangs. The act also bans large-capacity ammunition magazines, limiting them to 10 rounds.
The law did not apply to weapons that were already in legal possession.
Rail MountAny type of accessory that can be attached to a firearm's rail. Field GunA shotgun, generally stocked to shoot where it is pointed and of relatively light weight because one often carries it a great distance for upland birds, the consequent recoil not being an important factor because one actually shoots it very little. Down RangeThe area of a gun range where firearms are pointed when they are fired. The area of the range forward of the firing line. CCLAbbreviation for Concealed Carry License. MOAAbbreviation for Minute Of Angle |
