Clean and maintain your Czech Vz — yourself. A Note on Reassembly: Most of the firearms covered in this book can be reassembled by simply reversing the order of disassembly, carefully replacing the parts in the same manner they were removed. In certain cases, reassembly photos are also provided. If there are no special instructions or photos with a particular gun, you may assume that it can just be reassembled in reverse order.
During disassembly, note the relationship of all parts and springs, and lay them out on the workbench in the order they were removed. Hammer Strut Installation. Installing the hammer strut assembly is probably the most difficult part of assembling the Vz52 rifle.
Trigger Group Assembled. Function test the trigger group to insure it will release the hammer when in the safety lever is in the fire position, and not release the hammer when the safety lever is in the the safe position.
Hold the trigger back after releasing the hammer and reset the hammer. If it does not release, carefully polish the top rear of the hammer where the disconnector catches. Bolt Assembly The bolt assembly consists of the extractor, bolt body, firing pin, firing pin spring, firing pin retaining pin, ejector, and ejector spring. The extractor should not be removed from the bolt as it is hardened steel and easily fractured by levering it off the bolt body. Firing Pin. Insert the firing pin into the spring and then both into the bolt body.
Rotate the firing pin until the line on the firing pin matches the line on the bolt body. Manipulate the firing pin and ensure it moves freely. If it does, insert the firing pin retaining pin. If it does not, remove and examine the area where the firing pin retaining pin limits the firing pin travel. I have seen sever firing pins where there is a slight deformation on the edges of this cutout which put friction on the firing pin channel.
Carefully stone these burrs flat and reassemble. Firing Pin Alignment. Correct firing pin alignment is when the two lines meet. If the firing pin is not in this orientation, you will be unable to insert the firing pin retaining pin.
The ejector prevents the firing pin retaining pin from falling out. Insert the ejector into the ejector spring bottom. Insert the ejector into the bolt body with the flange perpendicular to the keyway. Press the ejector forward until you can grasp it from the front of the bolt body middle.
Extractor Spring. The extractor spring is a U-shaped piece of wire that snaps into a recess in the bolt carrier. The two arms press downward on either side of the extractor. Gas System Components. The gas system is both interesting and problematic. It is interesting because it keeps the recoil energy close to the barrel, as compared to a piston above the barrel such as on the AK The higher the impact of a piston, the more muzzle rise on recoil.
It is problematic because it requires a 22mm and a 23mm wrench for disassembly, which makes field cleaning difficult. Combined with the corrosive primers found on the Czech 7. Gas System Assembly. Follow with the gas piston, small end toward receiver.
Thread the actuator onto the barrel slightly past the point where there will be room for the actuator lock nut. Thread the lock nut onto the barrel until it is aligned with the first barrel thread. Unscrew the actuator until it stops against the lock nut. The lock nut uses a 22mm wrench, the actuator a 23mm wrench.
The connector transfers the piston energy to the drive spring plunger and causes the bolt carrier to cycle. Slip the connector over the drive spring plunger, slightly depressing the drive spring, and then slip the other end into the piston recess. Handguard Clip.
The handguard clip assembly includes the handguard clip, the handguard clip screw, and the handguard clip escutcheon threaded insert. The handguard clip is a double-armed piece of spring steel that latches the back of the handguard. Squeezing the two arms inward releases the handguard. This escutcheon should not be removed. Recoil Lug. The recoil lug assembly consists of the recoil lug, the recoil lug escutcheon, recoil lug screw, and recoil lug screw lock screw.
Earlier models did not have the escutcheon or the stock cross-bolt-. These were added to reduce stock cracking at the wrist. The recoil lug stops the bolt rearward movement, and acts as a camming surface like the M1 Carbine for securing the barreled action into the stock.
Recoil Lug Installation. Insert the recoil lug from the top, and the escutcheon from the bottom. Insert and tighten the recoil lug screw. Insert the recoil lug screw lock screw. Buttplate Assembly. Between the gas piston lighter colour and the locknut is the adjusting nut itself. Operating rod removed and placed on the right side. 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 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 — 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.
For this purpose, a stripper clip guide is milled into the front face of the bolt carrier, aligning with the magazine when the bolt is locked in the open position. 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. After pressure from the Soviet Union to adopt its 7. It is considerably less common and are generally found in better condition due to the vz. All of the vz. Military Wiki Explore.
