Flashbang (grenade)

A stun grenade, also known as a flash grenade, is a non-lethal explosive device used to temporarily disorient an enemy's senses. It is designed to produce a blinding flash of light and intensely loud noise "bang" of greater than 170 decibels (dB) without causing permanent injury. It was first developed by the British Army's SAS in the 1960s.
The flash produced momentarily activates all photoreceptor cells in the eye, making vision impossible for approximately five seconds, until the eye restores itself to its normal, unstimulated state. The loud blast is meant to cause temporary loss of hearing, and also disturbs the fluid in the ear, causing loss of balance.
The concussive blast of the detonation can still injure, and the heat created can ignite flammable materials such as fuel. The fires that occurred during the Iranian Embassy siege in London were caused by stun grenades.

Scattergun

A slang term for a shotgun.

Crown

The area inside the bore nearest to the muzzle.

Line Of Bore

An imaginary straight line through the centre of the bore of a firearm extending to infinity.

Boattail

The tapered rear end of a bullet. This design is used to increase ballistic efficiency at long range.

Accidental Discharge

An unexpected and undesirable discharge of a firearm caused by circumstances beyond the control of the participant(s) such as a mechanical failure or parts breakage. There are very, very few firearms related "accidents" and if the "Three Rules" are followed there will hopefully be no injury. Accidental Discharge should not be confused with "Negligent Discharge".

Open Frame

Refers to a revolver frame that has no top-strap over the cylinder.

Pigeon Gun

A double-barrel shotgun, with relatively tight choke boring and a relatively high-combed stock used for shooting live pigeons (euphemistically known as flyers) which normally rise when released. To better absorb recoil, a pigeon gun is normally heavier than a field gun as one shoots heavy loads and walks only a little. Because of the inevitable expense of this shooting discipline, pigeon guns are often built to a high standard of quality and reliability in deluxe grades with highly figured walnut stocks and fine engraving.

DA

Abbreviation for Double Action

Shotshell

Same as a Shotgun Shell.

Squib

An underpowered powder charge, usually caused by a fault in cartridge loading, often insufficient to expel a projectile from the muzzle of a firearm. If such a blockage is not cleared, the next attempted shot could cause the barrel at least to bulge, and very possibly to burst.
