The Definition of Birdshot
A type of shotgun ammunition which uses very small pellets with individual projectiles of less than .24" in diameter
designed to be discharged in quantity from the shotgun. The size of the shot is given as a number or letter--
with the larger number the smaller the shot size. It is so named because it is most often used for hunting birds.
The finest size generally used is #9 which is approximately .08" in diameter and the largest common size is #2 which is approximately .15"

A mounting point on a small arm that allows a bayonet or other accessory to be attached.
A rifle front sight with a extra-large, folding bead. Typically, in addition to the normal fine bead (which allows for more precision) the larger bead,
while at a cost of potential accuracy, is more readily acquired in marginal light. Also called a Gloaming sight
The point at which you are aiming the firearm at.
The substance which imparts movement to the projectile in a firearm. In a firearm, usually powder. In an airgun the propellant is air or Co2
Usually only found on black powder muzzle loading rifles and pistols,
pulling the rear (set) trigger converts the front (main) trigger to a light, hair trigger
(too light and sensitive to be carried safely in the field). While the front trigger is always at the ready,
if one has the time, using the set trigger feature may allow for a more accurate long-distance shot.
Operates using its own miniature firing mechanism (sear, spring and hammer) when cocked,
to multiply the force of a pull on the main trigger.
