Gun dynamics describes the physical causes of barrel and shot vibration, and the effect they may have on accuracy and consistency. It is employed to predict firearm performance, such as recoil , using theoretical methods and mathematical modelling techniques.
Comparison of milliradian (mil) and minute of arc (moa).. Since adjusting the point of impact to match the point of aim is relatively simple with any type of adjustable sights, the primary goal of accurizing is to increase the precision of the firearm, which is generally measured by looking at the dispersion of a number of shots fired at the same point of aim.
Attaching the barrel to the receiver using a barrel nut and a barrel with a shoulder is an alternative to action threads, which has been used in firearms such as the Sten gun and AR-15. Hand tools Quick barrel change systems is an increasingly popular alternative, as seen in for example SIG Sauer 200 STR, Roessler Titan or Blaser R8.

Since barrel length is limited by practical concerns to about arm's length for a rifle and much shorter for a handgun, increasing bore diameter is the normal way to increase the efficiency of a cartridge. The limit to bore diameter is generally the sectional density of the projectile (see external ballistics).
The scope base is the attachment interface on the rifle's receiver, onto which the scope rings or scope mount are fixed. Early telescopic sights almost all have the rings that are fastened directly into tapped screw holes on the receiver, hence having no additional scope base other than the receiver top itself.
The Ruger Precision Rimfire is a rimfire bolt-action rifle manufactured by Sturm, Ruger & Co. in the United States. The firearm has some visual similarities with the larger centerfire Ruger Precision Rifle , and both are marketed as budget precision rifles.
The Chiappa Rhino is an example of a pistol with a low bore axis. The SIG Sauer P226 is an example of a pistol with a high bore axis.. The recoil from a fired cartridge (and the action movement) exerts a rearward impulse along the bore axis, which is commonly above the center of mass of the gun.
