can you improve the cz452.....(17hmr)

andyone

I recently heard of someone removing some timber from there stock on a .22 to allow the barrel to FLOAT.... not having fired the gun i have to take the owners word that his actions improved the accuracy of the weapon.... the question i have is has any one done this to a cz452... in.17 cal.... and has it made a deadlier gun more deadly.....???

Hi mate
when I had my cz I used to put a washer in under the front lug hole to free flaot the barrel, now this worked for me

That works OK but it's better to sand some of the stock out to free float the barrel IMO

andyone

clivej,
sounds simple enough, but is there much to it.....and it the improvement worth the work?

Yes -just unscrew the 2 action screws and sand where the barrel goes NOT the action until when it all fits back you can run a folded sheet of paper down between the barrel and the stock without it binding AT ALL.
Unless you can already do that then there's no need to do it at in the first place.

do a search for trigger kits on E Bay for some tha are new or search for Brooks trigger kits with google. About €15 and are easy to fit.

My groups are 12mm @50 and were 4" when starting out first.

Dont bite my head off but CZ put the stud in for a reason. Not so us users can claim to know better. If the maker puts it in leave it in.
The trigger kit is differant though, yeah buy that.

clivej

What stud are you talking about??

People used float their varmint cz's .22 by removing a stud at the foregrip that connected up to the barrel. I had a cz .17 but didnt study it in great detail. I presume the metal fixing is common to a lot of Cz's.

A piece of paper couldnt slide down between the barrel and the timber until this metal fixing was removed.

andyone

come on time lord....... your throwing stuff in to the mix that your not sure about....i'm not ready to do any work on it yet..... but the man in me has me wanting to take it apart already.......i'll let you know about the stud or the lack there of..

clivej

Ok I know the stud your talking about it's called the front action screw.

Well here's what I did to my CZ Style 22lr to get it shooting good groups.

1- Made sure the barrel is floated. Check that a folded piece of paper can slide down the barrel between the stock and the barrel up to the first action screw. If not then sand away some of the stock until it does slide down freely.

2- Fitted the Brooks trigger kit. I used the thickest tube (less creep) and 2nd lightest spring. Bump tested OK.

3- Tried all the different ammo and found that my CZ will shoot Eley standard subs and Lapua club the best. It is important to do this and find the best ammo for your gun.

4- Never clean the gun bore until it stops grouping well (my 22lr 5000/7000 rounds so far ). Except before shooting for the first time to get the gunk out of the barrel.

i have three cz 452 ....one .22 limited edition fully floated fluted barrell....one .17 hmr which rubs the stock on right hand side....and one 1979 brno...not floated...all deadly accurate guns....shoot first before deciding what work needs to be done....most likely no work needed....just shoot like hell

That is the best advice in this thread

Just do the trigger - bookes, or Timney do a full replacement unit approx €95

time lord

Why would Cz not just sell the rifles with a floating barrel if the stud is truely not needed.

It does not make sense. They would save money by removing it from the manufacturing process.

If its there leave it there. I guarentee any rifle maker would agree with me.

It wasn't me!

To be fair, there's such an enormous culture of firearm modification across the world, the manufacturers clearly don't make faultless products every time.

On that note, I do think there's some confusion here. Any CZ I've personally had a look at has had no screw between the fore-end and the barrel. There's the sling swivel stud, but that hasn't prodtruded through the fore-end and contacted the barrel in any I've seen. So I suspect that time lord is talking about a screw into the action, and therefore can't see why someone would remove that. Floated barrel, not floated action, is what we're going for here. So as I see it, nobody is suggesting removing action screws to increase accuracy, and that wouldn't be good advice (despite the fact that I've seen guns with entirely floating actions as well, odd creations, so it's a concept that's out there, but not being discussed here).

So, in effect, there's no dispute with what you say time lord, because nobody's suggested removing action screws, and anyone whose sling swivel stud protrudes and contacts the barrel, well, they'd be right to remove it, harmonics and all that jazz. I do dispute however that factory rifles can't be improved on by the user - all evidence across the world points to the contrary.

Ok, there is some confusion here I've had 3 452's A 1969 which had 2 action screws 1 just before the trigger guard and 1 immediatly after the magazine, next 1 was new in 1999 it was a 452 american (no boarback stock)had same setup, the last one bought in 2005 was american stock but had 1 screw at rear of triggerguard into just timber and another front of mag going into action and a third going into a barrell lug. I think it depends on which variant of 452 you get.
As to free floating i inletted the stock on the first two and found a more consistent grouping. on my last CZ the third bolt on to the barrell limited the positive effects of freefloating I didnt remove the third bolt as this would have left only 1 bolt holding action to the stock and made it inconsistent in firing as the recoil could shift the barrel against the stock or vice versa, I traded the 2 month oldCZ for a Finnfire:D

Umiq88

Some of the cz models have a barrel lug i thought it was the hogsback lux models but may be wrong.

As for modifying a cz i have a heavy barreled .17 version and have totally floated the barrel and put in a trigger kit and has improved it a lot. The only other modification would be to bed the action but my rifle shoots consistantly well and ive no experience with this so not going near it.

Best thing you can do to make you rifle shoot better is put a decent scope on it and practice.

andyone

thanks to all for your advice..... i get the impression that the stud timelord is talking about is further up the gun......SYCORNED had the cheapest and easiest solution...... found a washer...... took the gun apart..... cleaned it.... and put it together adding this washer...... the barrel is now fully floating... and absolutly no sign of the stud timelord was talking about..... in my opinion the gun was very accurate to start with...i'm just trying to improve on perfection....my ammunition of choice is the Horandy brand... as it does the buisness on any bunnies that have crossed my path......even got one of the buggers the other night out at about 160+yards..... i haven't shot much paper with it.. but will have to to re zero the gun now...and if i'm not happy i'll just remove the washer and rezero...I'm all for pushing the gun to it's limits was hitting a 18" target at 380+yds...but the day was calm out.... and we don't see many of them around here.... thanks again to one and all......I'll let you's know what my groups are at a 100yds when the weather improves..... andy

oh and i have BSA 6-24x50 on it.... plenty good i think..

Sure does. I've a 1972 BRNO Mod II with a bolt about 3 inches down the barrell. Was actually planning an upgrade to a new CZ this week if the price is right. Old bessie has some pitting, the stock is cracked, and the crown is in bits ( farm rifle for past 20 yrs). Maybe it's time to send her to rifle heaven.

That will be a sad sad day..There a beautiful old rifle..would love to get my hands on one thats in reasonable condition

andyone

thanks again to one and all....... i was shooting today and i was impressed... the target shown.... is the small shoot'n'see on an A4 page 100yds down range... its windy as f**k here today but had to try anyway.... there are a couple of wild shoots... but when i was happy i put 20 rounds down range as quick as i could..... the wind was blowing right to left and i was aiming at the bull as best i could..... i wanted the shoots landing a little high as then i'd be bang on out at 120+yds.... on a calm day i'd say the shoots would be bang on....... i was happy any way..... thanks again to one and all

I put a lighter trigger spring in my .22 CZ452, a spring I found in my toolbox that just happened to fit nicely. I was shocked at the improvement. With the old setup I just couldnt tell when the gun was going to fire, I used to almost get dizzy holding my breath waiting for the sear to let go. The trigger was heavy and the creep was seemingly never ending. Now with the new spring it breaks like glass just when I expect it to, consistently.

dwighet

Andyone..
I have 2 sets of brooks trigger kits minus one spring and one sleeve which i have in my guns...your welcome to the rest of the springs and sleeves..
just pm me your address and i will slip em in the post for you... here is how to install them..its very easy and works a treat...http://cz452.com/springkit.html just make sure after instalation that your trigger isnt too sensative by slamming the bolt shut several times and bumping the rifle off the ground a few times..if the trigger doesnt go off your good to go

clivej

I have the second spring and the biggest tube. The trigger just takes up a tiny bit then it lets go. Just right for me.

I also gave the other bits away.

andyone

what can i say guys thank you very much for your help.... and the gun porn...... i've already downloaded them..... and am hoping to put them up on the bedroom walls........ kylie seemingly aint her thing.....lol:D:D

dont take me wrong hear as i know you mean all the best . but i would give no one this type of gear .

if there is a accident over a gun going off and some one gets hurt,some one will have to pay the piper .

a dealer will have insurance .

andyone

ah hello js.......no one should have a gun thats not safety concious,,,,,,, and i'd like to see you bring a claim against some company, who tells you not to tamper with fire arms.... hello thank god the world is not full of like minded people.... could you imagine having to fill paperwork out in triplicate, for your licence to be allowed to shave on your own...... relax there a bit.....

In all fairness Andy J.W has a point.. I would hate for an accident to happen and I was at fault for supplying the goods to yourself that caused the problem...

maybe you's are both right ... but lest we forget the famous saying.... guns don't kill people..... people kill people....... back to the drawing board so..... eric brookes it is....

its just me been about a bit

A bit OTT here.

If this was the case Eric Brooks would be getting sued every day.

Try here for the kits as well, about €12 + €2 for post and are the same as Brooks kit, they may be a quicker delivery time than from Brooks.

eric brooks has public liability insurance i would think .

i would think that's why jackson ,south yorkshire ,sako ,tikka, dont sell trigger kits to general public .,even e bay has a disclaimer.
but belt away i dont care i was just trying to be help full

I own the CZ 452 style .22lr and adjusted the nut to lighten the spring.

Hate to say this but you won't know how good a Brooks trigger kit is until you try a CZ 452 with one fitted in it.
It will remove all the creep and make for a lighter triger. The result is tighter, smaller groups.

Nemesis

Aye..but I might as well take things slowly so I can appreciate the differences.

But while I'm testing maybe I should place an order for the Brooks kit..wont do any harm having it on its way.

From what I read there can be problems ordering or rather receiving the Kit if you order directly.

Where is a good place to purchase a kit?

Just seen the link above......I'll go place an order!

Sad but true about the insurance

well guys here's a progress report......:(:(:( all went well untill i started drop testing the .17.......maybe i was banging it too hard.. but i don't think so..... i just wanted to make tripely sure that the rifle would not go of on its own accord...i had replaced the original spring...... drop tested it.... it failed that test.... so i put in the next spring..... and i tested it.... it passed my test... but for some reason a piece of the stock fell of up were the bolt slides in....to say i was sick is a understatement:(:(:(.. the stock has now gone off to someone local, to perform open heart surgery on it..... will hopefully have it back friday evening... looking forward to getting it back, weather permitting i should be able to zero it in over the week end.... will keep you guys posted.....

Hi All,

I got myself a Brookes kit for the CZ, can anyone recommend a gunsmith in the Dublin area to fit the new trigger kit for me? I wouldn't feel comfortable doing it myself even though I know its probably pretty easy..
PM me details either

Cheers,

BountyHunter.
