this is the tool i have used for dozens of stock removals, Its never failed me yet. Its a 1/2" chisel, Ground to fit the flathead screw, A 3/4" drive 1/2" deep socket & a hammer drive impact driver.

This is what it looks like assembled. I thought id share. Good luck

I use a bloody big screw driver from Cambodian tire and I wrap the handle with about 3 wraps of 1/16" rubber sheet. Delivers more than enough torque to break the loctite and start the screw off.

The secret is to hold the receiver in a vise with softjaws.
 
I've got a big hex-shank flat bladed screwdriver. I use a small wrench to turn it while I lean on the screwdriver. Never had a problem.
 
Some nice ideas in here... I never managed to get mine off... I was going to order a collapsible stock for my 858, but since I was under the impression that the f*ckin thing was WELDED in there upon trying to remove it, I just gave up on the whole idea. It literally feels like the screw head will give before the thread loosens (haven't tried applying heat with the blowtorch, as I was scared it would melt that POS plastic buttstock).

What on earth could've given CZ the idea that the buttstock needed to be coupled with the gun for the next 4000 years? I have an 1886 Martini Henry rifle (that looked like it's never been disassembled in 120+ years when I got it) and the same screw came out without being a PITA at all, lol! Now, a CZ 858.... whoooole different story! The only such rifle I ever ran into, actually.. and I've taken apart quite a few.

Anyway, I'm glad I came across this thread, thanks for posting!... Come to think of it, I guess I might use the vise and a breaker bar on mine when time allows. Worst come to worst the screw will break... and I'll have a fun time drilling out whatever screw part is left in the receiver.

:p
 
Removing a VZ stock is only second inthe PITA category of home gunsmithing tasks, first would be removing a M305 flash hider!:runaway:

I ground down a beat up chisel to fit the large flat head screw (folding stock), receiver in vice and a adjustable wrench to turn while I applied downward pressure, takes two to do it right!
 
MP5k, you said a 3/4" drive , I presume you mean a 3/8" drive.
I haven't done one of these, But I use a 3/8 " air impact wrench
for almost everything , The sharp hammering is what does the job,
If any one has a take of stock they don't need , I would be interested
in it as I have a new folder and am thinking that a full stock would be
better ( or both)
I am thinking about making full wood set for it, But would be nice to have
the factory stock as a template for the receiver end of the thing.
I have some elm wood that would look nice one one of these.
Sorry, I got a bit off topic.

You are right, I meant 1/2" drive. I havent found one that its failed on, But some can be tough. When all else fails there is always the sawzall, Providing you dont neeed the old stock. Ill bet there are a few of those stories out there!
