The standard Mini-14 was discontinued and the name became the family name for all Mini-14-type rifles. As of 2005, all Mini-14-type rifles are based on the Ranch Rifle design, with integral scope bases, a nonfolding ghost ring aperture rear sight, and a winged front sight similar to that used on the Ruger police carbine.

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.
Therefore, when the barrel recoils the inertial force from the breech produces a moment on the rear end of the barrel. This causes a wave to travel down the barrel which quickly overtakes the shot and results in a deflection of the muzzle before shot exit. Figure 6 shows the typical response of a tank gun barrel for an off-axis breech.
There are many forms of gun stabilization. The simple single-plane stabilizer only stabilizes on a vertical axis, and the two-plane stabilizer stabilizes both the vertical and horizontal axis. The mechanism usually includes an angular reference device such as a mechanical or optical gyroscope and servomechanisms. In the case of a tank, one ...
The tuned mass damper was introduced as part of the suspension system by Renault on its 2005 F1 car (the Renault R25), at the 2005 Brazilian Grand Prix.The system reportedly reduced lap times by 0.3 seconds: a phenomenal gain for a relatively simple device. [1]
A harmonic balancer (sometimes called crankshaft damper, torsional damper, or vibration damper) is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly. The harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator, water pump and ...
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.
Harmonic Drive SE strain wave gear set consisting of wave generator bearing (top left), flexspline cup (top right) and circular spline ring (bottom). Strain wave gearing (also known as harmonic gearing ) is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage ...
