VZ58: Cleaning & Maintenance Techniques

They don't necessarily clean rifles in combat everyday. Just clean it with solvents and oil it. Clean it really well in gas port area.

Thank you, I feel better now, what's the simplest way of cleaning the trigger assembly(preferably without dis assembly of the trigger mechanism) and do I have to disassemble the bolt and clean the firing pin or is there a different way cleaning the bolt and pin without dis assembling it
 
Excellent videos! Thanks for taking the time to put them together. Very helpful.

I have a bunch of questions that may help out others.

(1)
Water ends up getting/splashing on the trigger group once in a while. I don't pour the boiling water directly on the trigger group but stuff happens. Even though the trigger group is lubed what care should be taken in this situation. I have already found out that blasting the water off with air is not the best option as it drives it into the cracks and crevices. A cursory wipe gets a bit off but I'm wondering if this is sufficient.

Second part of the first question would be the cleaning of the trigger group. How often? And how lubed should it be? Lubed and buffed dry or left wet?

(2)
In regards to the gas piston tubes(?). I'm assuming these should be scrubbed quite diligently? The port coming out of the barrel on mine gets black as night with soot as well the outside the gun and into the front hand guard near the port. I've taken to scrubbing that area out with an old tooth brush and solvent.

(3)
In regards the oiling of the gun. I personally oil every part of the gun, inside and out. For example, including parts such as the insides of the gas tube ports. Is this over-kill or standard procedure? And how oily is oily enough? I actually had mine so wet when I first got this gun that the first round of the day left a spray of oil on my glasses. Chock one up for the use of eye protection.

So is there really a point of the gun being too wet? Is wet to the touch on internal components over-kill? Will a too-oily gun, internally, attract more soot than a buffed dry one, and be harder to clean in the long run? Is buffing internal components dry after oiling really leaving enough oil behind?

A personal experience with oiling... I have oiled the gas piston too much once. I basically sprayed oil in the port that goes to the barrel. After shooting I found that, on the piston itself, the end that meets the gas pressure got a lot of baked on soot. I had to use solvent and a brass brush on it. Subsequent light oiling left it sooty but not baked on. In the first case I'm guessing the excess oil was probably cooked but the temperature.

In regards to the water issue, boiling water makes the metal really hot and that will make the water evaporate, too much oil is not good, I personaly apply a thin layer of oil.

The locking plate is only retaining the one pin that the sear is on.

actually the locking plate holds two pins in , the sear axis pin and the trigger axis pin but you are correct that it doesnt hold the safety lever .

i just had a blank moment , the safety lever is held in by the dual purpose sear spring (its the weird looking one in the rear) and the lever shouldnt be easy to pull out but it can by force.

may i suggest bend the spring up slightly and that will put pressure on the safety lever and if it still comes out easily then replace the sear spring or the safety lever .

It is the metal T that locks the trigger sear pin & saftey. Shown just above the trigger in this picture.
 
is any one getting spent cartridges not ejecting ? My 858 loves to shear the lip off the cartridge so I have the pleasure of throwing a cleaning rod down to jam it out. Its pretty irritating. I know its too hot but I mean If I had full 30rd clips and unloaded two down range guaranteed it would not eject half way through the second clip. What am I doing wrong and does the 58 do this as well? Whats the difference between jelly and jam? you cant jelly a spent cartridge out.
 
Re the safety : is the set screw in? Or did you have a C clamp on your safety?

Re bluntOtrauma's Q : what ammo are you using?

Have you cleaned the chamber? The lacquer from surplus ammo can build up in there and cause cases to stick.
 
it goes through a pretty thorough cleaning after every use the ammo I am using is Sieller and bellot. The chamber is usually pretty clean ...... mind you I am going through 500 rds a day perhaps its just "plaque" that is building up ?
