They are durable, affordable, extremely reliable, combat accurate, have a low bore axis
, are easy to clean, have few parts, parts, are affordable, readily available and easy to replace without the need of a gunsmith.
Kahr utilizes an "offset barrel" design that allows the trigger mechanism to be built higher in relation to the bore axis
and placing the shooter's hand higher on the gun.
After all, one of the advantages of a striker-fired mechanism has to do with the relationship between bore axis
and shooter comfort.
The shallow frame combined with the straight grip and splinter fore-end of the Iside minimize the distance from the bore axis
to the palm of the leading hand.
As a scope is mounted well above the bore axis
, the bullet must cross the line of sight at about 25 yards and then again cross the line of sight at the point where the rifle is sighted in.
For tactical rifle and carbine platforms they offer flip-up backup iron sights as well as angled offset sights which come into play with a quick rotation of the rifle around its bore axis
In the first study, the effect of the two types of direction of in-cylinder mixture stratification on combustion was researched: the first shape of in-cylinder mixture stratification is parallel to bore axis
and the second shape of that is parallel to cylinder axis.
My colleague Jim Tarr would gripe that this pistol has a high bore axis
, and he'd be right.
When the rotor eccentricity refers displacement axis rotor stator bore axis
In that case transverse force, that is a component of a swash plate reaction force, inclines a piston axis with respect to a cylindrical bore axis
, which leads to high contact stresses where the piston contacts edges of the cylindrical bore and, therefore, to higher friction forces and reducing efficiency of the hydraulic machine .
On these rifles, whether iron-sighted or topped with optics, the line of sight is distinctly higher than the line of the bore axis
The result is a far more concentric and consistent alignment of the bullet with the bore axis
, more positive and non-distorted land/groove engagement, consequent enhanced accuracy and less wear and tear on the bore.
