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.
A Federal Firearms License (FFL) is a license in the United States that enables an individual or a company to engage in a business pertaining to

A steel bolt, mounted transversely through a rifle stock just under and behind the front (and sometimes rear) receiver ring,
sometimes concealed in the wood and usually against which the action is carefully bedded. When properly fitted, it helps distribute the recoil
and reinforces stock at the point where wood has been removed to accept the action. Recoil crossbolts can be recognized by the
flush-mounted circular steel fittings on the side of the stock, but are sometimes finished with contrasting wooden plugs and
sometimes concealed completely. Also called Reinforcing Crossbolt.
