Design Details
The vz. 52 is a shoulder-fired semi-automatic rifle with a tilting-bolt locking mechanism powered by an annular short-stroke gas piston system. The bolt is locked by two lugs that recess into slots machined into the receiver. However, unlike most vertically-locking breech mechanism, the rifle's bolt has the unusual feature of tipping the bolt frontally to lock the mechanism, whereas other tipping bolt designs tip the bolt to the rear. The piston is actuated by residual gases from the bore, vented into a sleeve surrounding the barrel to overcome the inertia of the bolt carrier, bolt and the resistance of the return spring in order to unlock the chamber, eject the empty cartridge casing and then introduce a new round into the chamber upon return to battery.
The barrel is press-fit and pinned into the receiver. The manual safety switch is placed inside of the trigger guard and is manipulated by the shooter's index finger. The trigger mechanism closely resembles that used in the American M1 Garand semi-automatic rifle. The cocking handle is integrated into the bolt carrier and is located on the right side of the rifle; this arrangement enables the shooter to reload the rifle without disturbing his aim.
The rifle is equipped with open-type iron sights with a hooded front post and V-notch rear sight placed on a sliding tangent, adjustable for elevation between 100–950 m. The rifle can also accept day and night-time optics that interface with an optional, receiver-mounted side rail. The one-piece pistol grip stock is carved from either walnut or beech and stained a yellowish-brown color; the stock has a hollowed butt which is used as a storage compartment for a cleaning rod, oil bottle and accessories. The rifle has an integral blade bayonet which folds into a recess carved into the stock on the right side.
The vz. 52 feeds from a detachable box magazine with a 10-round cartridge capacity but could also be rapidly recharged from stripper clips with the bolt retracted. For this purpose, a stripper clip guide is milled into the receiver top behind the ejection port. This is the primary method of reloading the rifle as infantrymen were only issued 2 magazines per rifle. It ejects cartridge cases vigorously forward and to the left.

Famous quotes containing the words design and/or details:
“To nourish children and raise them against odds is in any time, any place, more valuable than to fix bolts in cars or design nuclear weapons.”
—Marilyn French (20th century)
“Patience is a most necessary qualification for business; many a man would rather you heard his story than granted his request. One must seem to hear the unreasonable demands of the petulant, unmoved, and the tedious details of the dull, untired. That is the least price that a man must pay for a high station.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
