By repeatedly firing a given projectile with the same charge, the point where the shot fell below the bottom of the bore could be measured. This distance was considered the point-blank range: any target within it required the gun to be depressed; any beyond it required elevation, up to the angle of greatest range at somewhat before 45 degrees.

The M1156 Precision Guidance Kit (PGK), formerly XM1156, is a U.S. Army-designed precision guidance system to turn existing 155 mm artillery shells into smart weapons ...
Unlike the many early 3D-printed firearm designs, which were overbuilt in order to withstand the pressures and strain on the material from modern gunpowder cartridges, the Reprringer is small and only slightly larger than an equivalent gun made from steel.

A drawback of using the naked eye to boresight is that it can be difficult due to the tunnel vision and lack of brightness, especially with longer-barreled guns. A more advanced method of boresighting uses a collimator boresighter, an optical attachment similar to a scope sight, which fits onto the muzzle end of the barrel via a bore-diameter ...
As with their air-actuated cousins, powder-actuated guns have a muzzle safety interlock. If the muzzle is not pressed against a surface with sufficient force, the firing pin is blocked and cannot reach the load to fire it. This helps ensure that the gun does not discharge in an unsafe manner, causing the nail to become an unrestrained projectile.
Mark III free gun reflector sight mk 9 variant Another type of optical sight is the reflector (or " reflex ") sight , a generally non- magnifying optical device that allows the user to look through a glass element and see a reflection of an illuminated aiming point or some other image superimposed on the field of view .

Reflector sights were invented as an improved gun-sight and since their invention they have been adapted to many types of weapons. When used with different types of guns, reflector sights are considered an improvement over simple iron sights (sights composed of two spaced metal aiming points that have to be aligned). [16]
