The Definition of Comb
The top of a gun's stock, where a shooter rests his cheek when mounting a gun.
As it is the top of the stock that determines the position of
one's eye, and one's eye is the rear sight on a shotgun, the position of the comb
is very important in determining the proper fit of a shotgun.

A clip IS NOT a magazine. A clip is used to load a magazine.
A clip is a simple, disposable narrow spring-lined channel-rail
that is used to store multiple rounds of ammunition together as a unit, ready for insertion into the magazine of a repeating firearm.
This speeds up the process of loading and reloading the firearm as several rounds can be loaded at once, rather than one round being loaded at a time.
The term clip commonly refers to a firearm magazine, though this usage is absolutely completely totaly 100% incorrect.
In the correct usage, a clip is used to feed a magazine or revolving cylinder,
while a magazine or a belt is used to load cartridges into the chamber of a firearm.
in which cartridges are supplied for military weapons. The shooter positions the clip
vertically above the firearm's magazine, then pressing down with the thumb,
slides the cartridges from the clip and down into the magazine.
A type of gun barrel rifling where the traditional lands and grooves are replaced by "hills and valleys" in a rounded polygonal pattern, usually a hexagon or octagon.

A small lever mounted to the cocking piece of a Winchester Model 70 rifle, rotating on a vertical axis from front (Fire),
halfway back (Safe, but allowing bolt movement), and fully back (Bolt and firing pin locked Safe).
While, like the Mauser, commendable for locking the firing pin instead of just the trigger,
its fore and aft movement is both easier to operate and it allows lower mounting of telescopic sights,
reducing parallax between the line of sight and the line of the bore and increasing the range of
distances for which the scope may be reliably sighted-in.
Also 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.
An imaginary straight line through the centre of the bore of a firearm extending to infinity.
