bead sight

He aimed over the bead sight and pulled the trigger.

Over the bead sight he saw the Old Man's startled face.

He leaned out quickly, dropping the front bead sight on the Blazer's left rear tire.

Pilots were also given the option of having ring and bead sights mounted on the top engine cowling formers.

An express open sight with big rear sight and brass bead sight and single stage trigger are standard.

While bead sights may be acceptable on sporting shotguns, they are best avoided for use on combat shotguns.

The 12-gauge ready again, Manning swung the front bead sight toward an IRA gunner with long wavy hair.

Iron sights or a low magnification telescopic sight are needed for accuracy, rather than the bead sight used with shot, and an open choke is best.

Sights vary from model to model, from simple bead sight to a receiver mounted ghost ring or an integrated base for a telescopic sight.

When first introduced the marker featured a fixed barrel assembly referred to as a "unibody" combined with a modified Crosman air pistol frame and brass bead sight.

Bead sights are inferior in practical accuracy compared to rifle and ghost-ring sights, as they provide no rear sight to verify correct alignment with the front sight.

The weapon was normally fired from periscope depth using a simple bead sight on the end of the gun aligned with the target through the periscope at a range of around 1200 metres.

The primary advantage of bead sights is that they do not interfere with the shooter's field of vision, allowing extremely rapid target acquisition, which is essential for fast moving targets such as clays and game.

The first slug barrels were cylinder bore barrels (no choke) outfitted with rifle sights, which are far better suited to accurate shooting of still targets than the standard bead sight used for shooting small, moving targets with shotshells.

Slug rounds, if available, can extend the effective range of the shotgun to 100 meters (although this is also dependent on the shotgun's sighting system; rifle sights and ghost ring sights will allow the average shooter to effectively engage human-sized targets at considerably greater distances than with a bead sight).
