The bore axis of a firearm is the longitudinal axis through the geometric center of the gun barrel. In a rifled barrel, the projectile (bullet/ball, pellet or slug) will spin around the bore axis as it goes through the barrel.
Boresighting is a process of placing one's line of sight down along the bore axis.

third method simply reports the angle of the grooves relative to the boreaxis, measured in degrees. The latter two methods have the inherent advantage...
cartridges, its most distinctive feature is that the barrel is on a much lower boreaxis, as the Rhino fires from the lowermost chamber of the cylinder rather...
barrel(s) are hinged much like a door and rotate perpendicularly to the boreaxis to expose the breech and allow loading and unloading of cartridges. A...
available. The Strike One pistol features a low boreaxis as the distance from the barrel central axis to the top of the grip is 12 mm (0.47 in). Other...
the bore to the other side. The rocking will first align the gauge with the boreaxis and the act of moving the handle to the other side of the bore will...
The primary reason for muzzle rise is that for nearly all guns, the boreaxis (longitudinal centerline of the barrel) is above the gun's center of mass...
composed of two components mounted perpendicularly above the weapon's boreaxis: a rear sight nearer (or proximally) to the shooter's eye, and a front...
mouth'), or blowing edge, of a hotchiku is closer to perpendicular to the boreaxis than that of a modern shakuhachi, but this is mostly a choice of the maker...
alignment with the boreaxis, and supported by a metal disk to prevent penetration of the over-powder wad during acceleration down the bore. The tips of the...
aligned with the bottom of the cylinder instead of the top. This lowers the boreaxis (line of the barrel) which directs the recoil in line with the shooter's...
of ammunition which lie in two rows facing left, offset 90° from the boreaxis. As the cartridges are pushed back by spring pressure and arrive at the...
position during firing the rollers rest on parallel surfaces relative to the boreaxis on the bolt head ensuring a full lockup. Upon firing, rearward force from...
"straight-line" recoil configuration and an elevated sight line over the boreaxis. The inline design helps reduce muzzle rise during automatic fire. Details...
undercut trigger guard section. Per SIG Sauer, the P365 has the lowest bore-axis ratio of any handgun currently made. Sights are green tritium three-dot...
over pistols with pivoting barrels (like the U.S. M1911 series). The low boreaxis of the vz. 82 provides for less muzzle rise and quicker follow-up shots...

perpendicular distance between the sight and the weapon's launch axis (e.g. the boreaxis of a gun)—generally referred to as "sight height"—can induce significant...
