VZ58 Rifle Details
Features Vz. 58 P The spring-loaded extractor and firing pin are both dwelling inside the breech lock, while the determinate ejector is located at the base of the receiver. The weapon does not have a square rotating hammer but is striker-fired up and the striker is a harden bar hollowed from one end more or less throughout its entire length to accommodate its own operating spring. At the open end of the striker, a plate is welded and there is a groove cut in each side of this to slither on the beneficiary guide handrail. This hammer-striker enters the void bolt and drives a fully hovering firing pin onward with each shot vz 58 accessories/ vz58 accessories/buy vz 58. The rifle uses a trigger machine with a handle-type fire mode selector, which is also a manual well being against unintentional discharge. When the selector switch is placed in its rear place ("1"—sole fire) the sear is halt and the left striker corral is alternate by the disconnector, which is depressed by the bolt hauler after each shot and is thus disconnected from the striker grab. The frontward surroundings of the selector knob ("30"—habitual fire) disables the disconnector, and the left striker collar meshes with the sear mechanism. The middle ("safe") setting with the selector lever pointing vertically downwards, mechanically lowers the trigger bar and the disconnector so there is no relationship between the trigger and the semi-repeated sear which holds the hammer. The rifle also has an internal protection, which prevents the weapon from discharging when out of battery. The correct striker-hammer grapple disables the striker-hammer, and it can only be released by pulling the allege handle back and raising the weapon. Sights The rifle's iron sights consist of a fully adjustable front post and a tangent rear sight with a sliding nick with assortment denominations from 100 to 800 m, accommodated every 100 m. Besides this, the left side of the rear sight leaf is noticeable with the correspondence "U" (univerzální), for snap shooting, firing at moving goals and night combat at ranges up to 300 m. The front sight base also serves as a mounting stage for the vz. 58 edged bayonet. Accessories Additional equipment supplied with the rifle comprise: 4 standby magazines, a publication pocket, vz58 bayonet and covering, clear out clash, quiet cap, oil bottle, unified toss, front sight modification tool and a threaded empty-firing adaptor butt stock for vz 58

About the Author
A 16 g rifle bullet traveling 230 m/s buries itself in a 3.2 kg pendulum?
A 16 g rifle bullet traveling 230 m/s buries itself in a 3.2 kg pendulum hanging on a 2.8 m long string, which makes the pendulum swing upward in an arc. Determine the vertical and horizontal components of the pendulum's displacement.
vertical m
horizontal m
This is a momentum - Kinetic Energy balance problem. We can ignore tye length of the string until we need to do the trig to calculate the x and y displacements
Mo = mass * velocity
bullet: 0.016 kg * 230 m/s = 3.68 kg*m/s
Momentum is conserved ==> Momentum of pendulum + bullet = mo of bullet
bullet + pend: 3.68 = (3.2 kg + 0.016kg) * v
v = 3.68 /3.216
v = 1.14 m/s
Now figure KE
KE = 0.5 Mv^2 = 0.5 * 3.216 * 1.14^2 = 2.10 J
PE = KE
PE = MGH
MGH = 2.10
3.216 * 9.8 H = 2.10
H = 2.10 / 31.52 = 0.06 m that is y
hypotenuse = 2.8 m
