Moderator thread - CZ452 Varmit

[marlin.45]

Just picked up the new 'toy' and decided not to go with the Sako mod that they were trying to sell me for £40 and use one that a colleague had given me gratis.

 

So get home to fit the free mod and....it's the wrong thread. Now he removed it from an .22RF Anschutz so I thought that the CZ would have the same thread - WRONG!

 

So what thread do I have on the Varmit 22LR? The bumph states 'Still' or 'PH' but what is the most common? Any clues looking at the thread? 1/2"x20 UNF?

 

All suggestion gratefully received before I cart the rifle to the local dealer and pay through the nose for one that fits.

it should be half inch. standard mod, can you get another mod from someone to try.

 

it could have been on a 5/8" threaded barrel.

Iv just bought a Parker Hale mod for my CZ 452 .22lr Lux, fits perfectly.

[marlin.45]

Off to the range tomorrow and one guy has a 10/22 with a mod so I may be able to try that.

 

Found two thread options standard 1/2"x20 UNF thread or 1/2"x28 UNS thread. But the later is not as common. Actual thread looks around 1/2" with 11mm of exposed length.

 

Mark,

 

How much do you pay for 10rnd mag for yours? Dealer wanted £30 each.

 

Frank,

 

What thread was it?

It says in the instructions: to fit thread half x 20 t.p.i ( half inch long).

[markbivvy]

1/2"x20 UNF thread thats the one, paid £25 for my 10 shot mags, but as everthing else they will have gone up, see em for resale at about £20 on the bbs.

i have a feeling the next mod you try will fit.

this will beas franksays 1/2" unf. standard.

[markbivvy]

marlin.45

you have pm.

[invector]

I use a SAK mod on both my .22 and .17HMR CZ Varmints.

[marlin.45]

Well at the range the guy turned up with the Ruger 10/22 and it is the same thread as the CZ - but he doesn't know what thread he has

 

So I'm 99% sure it's the standard one and not the Parker-hale alternative. So if anyone has a 10/22 and knows their moderator thread and if this is the only one it is offered in from the factory.............................................

 

 

 

And the result from the range is this rifle is a tack driver! But I would have expected no less from a CZ really should I? Stuck 50 rounds through it and it's bedding in nicely. Just need the mod and a 10rnd mag now.

 

 

And a bipod

 

 

 

And float the barrel

 

 

 

And.....................

1/2"x 20= rimfire

1/2"x28=full bore

but i might be wrong, if iam someone will correct it this evening.

[marlin.45]

Ordered a black SAK in std thread this morning.

 

Hope it fits

[Dunkield]

Marlin,

 

I have got a .22 CZ and a SAK and went straight on, good gun good mod.

 

I paid £26 for my 10 shot mag, all plastic but still cheaper then cenrefire mags :*)

 

Mark,

 

The thread on my .22r/f and my .223 are the same pitch, so it looks like as with most most things there is no standard standard!!

[markbivvy]

The thread on my .R/f and my .223 are the same pitch, so it looks like as with most most things there is no standard standard!!

 

 

as far as i know, and i could be wrong.

the thread on the cf rifle should be longer than on the RF rifle. the cf has more pressure. did you have them threaded private.

[Dunkield]

Mark,

 

The centrefire thread is longer, I was hoping to use the thread protector from my .22 on my .223 but it is too short.

 

The threads themselves are the same pitch though that is what I was saying they are both 20 tpi.

[Hubertus]

how precise is the cz 452 varmint?

Can you please post some targets?

I would be very pleased

 

Thanks, Hubertus

[dunganick]

 

picture dosent do the group justice

 

but it measures .139 of an inch once the bullet size has been taken away from it (proper bench rest measurement)

[marlin.45]

Dunga,

 

What was the distance for that group?

 

Plus cartridge?

Edited December 20, 2005 by marlin.45

[dunganick]

50 yards

 

and standard eley xtra's

[Hubertus]

that is quite a nice group!

Is that a normal group for your cz 452? That means looks every group with that ammo like that or have you choosen the best group?

 

Have you ever tried other ammo? How precise was that and how far out compared to the eley extras?

 

thanks for your answers

Hubertus

[Frank]

Good shooting Nick.

My CZ 452 Lux does the same thing.

FANTASTIC RIFLES.

[dunganick]

average group is around .220 of an inch, that was an exceptionaly good one the standard eley are pretty consistant, but you still get the odd fast/slow one which knackers the group. it will hold very similar accuracy to 75 yards, but at 100 you will struggle to keep it inside an inch. took me about 5 groups to get it inside an inch the others were more like 1.25

 

i have never tried any other ammo with the gun, ive never felt the need to.

 

i am going to experiment with weighing the rounds and maybe if i have the time checking neck thickness. but at the moment i havent been to a range in 2 months so havent had a chance.

[Hubertus]

thanks for your answer Dunganick.

That is really a nice rifle you have.

 

Hubertus

cheers mate
