Moon Clip

A moon clip is a ring-shaped or star-shaped piece of metal designed to hold multiple cartridges together as a unit, for simultaneous insertion and extraction from a revolver cylinder. Unlike a speedloader, a moon clip remains in place during firing, and after firing, is used to extract the empty cartridge cases.

Trigger Jerk

Yanking the trigger back abruptly, thus pulling the muzzle of the gun downward at the moment the shot fires.

HMR

Abbreviation for Hornady Magnum Rimfire.

Parkerizing

A chemical phosphate process developed during the second world war to provide an economical, durable and non-reflective surface finish to military firearms.

Co-Witness Sighting

Co-Witness Sighting is the use of any iron sight mounted onto a rifle that is fitted with an optical sight as a primary sighting system. They come in two basic configurations, fixed or flip-up. The idea is that if you align your red dot and your iron sights you have a backup aiming system on the gun.

Federal Assault Weapons Ban

Part 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.
Because this law was not renewed by congress in 2004, the ban was lifted.

Single Action

An action type that when the trigger is pulled, the only thing the trigger does is drop the hammer (or striker). This applies to both revolvers, semi-automatic and automatic guns. On a single action revolver, the gun must be manually cocked before it can be fired. With semi-automatic and automatic guns that are single action, the only thing the trigger does is drop the hammer, striker or firing pin onto the cartridge. Then the firearm is cocked again when from the recoil of the fired round. A firearm that the gun is cocked and the hammer drops when the trigger is pulled is a double action gun.

Round Gun

Slang term for a revolver.

Choke

A constriction at or near the muzzle of a shotgun barrel that affects shot dispersion.

DAO

Abbreviation for Double Action Only. Is a type of firearm in which the firing mechanism cannot be cocked in a single-action stage. Firing always occurs as a double-action sequence where pulling the trigger both cocks and then fires the gun.

Railgun

A railgun is an electrically powered electromagnetic projectile launcher based on similar principles to the homopolar motor.
Using a magnetic field powered by electricity, a rail gun can accelerate a projectile up to 52,493 feet (16,000 meters) per second.
A railgun consists of two parallel metal rails (hence the name) connected to an electrical power supply. When a conductive projectile is inserted between the rails (at the end connected to the power supply), it completes the circuit. Electrons flow from the negative terminal of the power supply up the negative rail, across the projectile, and down the positive rail, back to the power supply.

WC

Abbreviation for wadcutter.

EDC

Abbreviation for Every Day Carry

WTI

Abbreviation for Wound Trauma Incapacitation.

Bottlenecked (Bottle Necked)

A type of cartridge whose bullet diameter is substantially less than the body diameter of the casing.

Scope Blocks

A pair of small dovetailed steel bases, screwed usually one to the barrel and one to the front receiver ring of a rifle, to accept mounts for target scopes such as the Unertl where the scope is allowed to move forward in the rings under the recoil of the rifle and which typically carry the windage and elevation adjustments in the mount.

Underlug

The locking lugs on a break-action firearm that extend from the bottom of the barrels under the chamber(s) and connect into the receiver bottom.

Break Action

A firearm whose barrels are hinged, and rotate perpendicular to the bore axis to expose the breech and allow loading and unloading of ammunition.

Rimless

A cartridge in which the base diameter is the same as the body diameter. The casing will normally have an extraction groove machined around it near the base, creating a "rim" at the base that is the same diameter as the body diameter.
