I like many others recently got a CZ858 and I'm wondering what methods you guys use to clean yours. When shooting corrosive, do you do a full detail strip and disassemble the bolt? Or do you just clean the barrel, piston, and bolt surfaces?
 
Strip it

Pour boiling water down the barrel while the bolt, piston and whatever small pieces are soaking in boiling water. The bolt is easy to dissasemble

Spray it with a compressor to get the water out and dry it out

Light coat of oil


that simple my friend, enjoy :p

I'll try disassembling it now and see how it goes, thanks for the advice kind sir

This works awesome. The first patch through the barrel after the water has so much black gunk!
 
I mix a little Ballistol oil with the water and use that milky solution. Leaves a film of oil. Start the process as early as possible because delay means corrosion.
 
Shoot 100-1000 rounds all day blazing.
Step 2: bring it home, and strip out the bolt
and piston parts.
Step 3: is boil kettle of h20.
4: make sure your bolt and piston parts lay in the drain of your sink.
Step 5: hold your (VZ858) reciever/barrel Assy. overtop of the parts and dump water through the chamber and through the gas port.
Then lube and re-assemble when dry.

Takes an hour. Maintain your firearms people.

when you say "strip out the bolt" do you mean disassembling it down to the firing pin? Or can I just leave the bolt intact? I can't see the bolt being exposed to the gasses that much
 
I find that you will get carbon inside the bolt which may (my theory) be a result of the way the firing pin is designed - 3 vanes like an arrow. I like to get all the carbon fouling off that I can so I scrub the parts in the hot water. Then again, it is preference as I can turn cleaning into hours of scrubbing / solvent / G96 / oiling etc. which is a round about way of saying I want some time to myself in the garage. However, I am also the guy that posted a thread about a FTF on the 58 because I left a cleaning patch inside the bolt and the striker - bless its soul - was still able to fire 7 rounds.

Nope.
Don't touch firing pin.
Only if it is stiff/ doesnt rattle when shaken. Spray with pressured lube cleaner/whatever flavour of choice.

Otherwise just hot water and then followed by lube oil.

-make sure you can hear the pin "click" back and forth when held by your ear with a shake. The sound is faint.

Re assemble. *Light-* oil for all.

Wipe excess away with a rag.
