CZ 457
- Thread starter A-Rob
- Start date
So I’ve got almost 750 rounds down the barrel now. After 500, she really tightened up!! Here’s a 50 shot group at 275 yards this morning with a 6 mph head/cross wind. The first shot, that is way right, was my first guess at the wind. This is a 7x8” steel target for size reference.

Hey guys I’m having trouble finding some extractors for a 457. If anyone could lead me in the right direction I’d appreciate it. Thank you
Welcome to my world…I contacted Cz and was told they have no idea when they’re going to restock. I think I’ve looked everywhere imaginable. I did happen to come across a 455 extractor but wasn’t sure if it would work in the 457. Looks the same but you never know.
Good luck
Check with lilja. They have a prefit, and I believe they well install them too.
CZ 455/457 22LR - Lilja
These barrels are a true match-grade barrel, we only have one grade for all of our barrels, our best. All of these barrels are made from 1" diameter 416 alloy rifle-barrel-quality stainless steel. Every barrel is drilled, reamed and rifled in our shop followed by a stress relieving heat...

I've read some pretty negative posts concerning Lilja's barrels here over the past several months. My experience with Lilja 22RF barrels is limited to one titebore blank I ordered from them for a CMP Rem 40XB that I had Jonathan Elrod at Modacam Rifles convert to a repeater using V-22 mags back in 2015. I ordered the blank in Rem sendero contour to finish at 26" - my thinking at the time was to keep the finished rifle as close as possible to my CF PRS rifles. I did the fitting & chambering on it, and also did a Krieger blank in the same contour, but finished at 22" at about the same time. I've shot this rifle more with the Krieger barrel than with the Lilja, but have enough experience with both to make a valid comparison. The Krieger is a hammer, comparing favorably with Bartlein & Kriegers on a couple of my Gen 1 V-22 repeaters - but the Lilja consistently shoots groups just a bit tighter.
Since then, I've fitted & chambered barrel blanks from Bartlein, Benchmark, several more Kriegers, and several Shilen select match ratchet rifled blanks for a couple of Gen 1 V-22s, one Gen 3 V-22S, and several CZ 455/457s. That single Lilja is still somewhat of a standout where accuracy's concerned, and may be the single most accurate barrel I've done for a repeater. The only thing I've noticed is that it likes to be cleaned every 120 or so rounds to maintain its best accuracy, but all I'm doing is a couple of wet patches (using Ed's Red), followed by a couple of dry patches.
Note that I have no experience with any of the pre-fit Liljas, and the Shilens I've done for the CZs were all glue-ins, allowing me to omit the cuts for the grub screws their OEM barrels have. Aside from a JGS Nevius reamer I used on a Shilen for my V-22S, all the other barrels were chambered with a PTG EPS reamer. I have no idea what reamer(s) Lilja uses on their pre-fits for bolt rifles. Certainly not a definitive study in typical quality of Lilja barrels, but I wanted to throw that out there for anyone considering buying one for a CZ455/457.

They will install it for you for an additional 50 bucks:
With Lilja it is true about the tenon diameter. With the barrel Lilja provides a set of five shims, .001 - .005., which allows you to set the headspace. I recently got one of their barrels for my 457. I set the headspace at .043. I took it out yesterday for the first time and put 75 rounds through the barrel. I really can't speak to the accuracy because of my skill level.
In a paycheck or two, I’m going to order a lilja prefit. Seems to be the way to go.
I put a Lilja prefit varmint contour in my 457 and couldn't have been happier. CenterX is a consistent performer at <.5in groups at 50yd. SK Std+ also does very well just has a flier every couple of groups. Fed Automatch also does well for plinking and higher volume shooting.
I can't remember what I set my headspace at. .043 or .042 sounds about right from what I can remember though. At one point I was going to play around with headspace and see what gave me the best accuracy. However I've been satisfied with the accuracy (and a bit lazy) so I haven't tried tested it.

I came second in production class in my first ever PRS match with my MTR today, and 24th out of 60+ overall. Took home a Triggertech cert.
Sorry for the super late update. Work has been crazy. This is at 100m today with sk standard out of my pro varmint with a ~3-5mph wind. My rifle seems to definitely prefer sk long range, but I ran out.

I have a Timney trigger kit for the CZ455. The CZ factory trigger with a Yodave spring change was a much better than the Timney. I Hope the Timney trigger for the CZ457 is better than what they built for the CZ455.
I should have mine in by this weekend. Will let you know how it compares to the OEM with Yodave spring change. Right now it's at 1lb 3oz. smooth with no creep.
I've been pleased enough with the factory triggers on my 457s after getting them adjusted down to a pound or just over to leave them alone. But after shooting my V-22S BR/F-class rifle with the Flavio Fare trigger set at a couple of ounces, I can see why someone might be wanting a lighter trigger for their CZ 457. If I were going to invest in changing out one of mine, I'd go with BScar's 2-stage trigger.
I'm waiting for a flat version of the Timney. With the YoDave spring (and BScar's trigger pin with E-clips), I've reduced my pull to around 9oz with minimal over- and pretravel. This is good enough for now, since what I really want is the flat shoe.
$200 shipped, get on the wait list. Mine feels as good as my Jewel on my UL rifle. Mine is set as single stage 3oz for RFBR.
Positively sick rig!!!....and excellent shooting to boot!
keep us in the loop. I'm on the Bscar trigger wait list. I'm in no hurry with a similar set up as yours.
BTW - I installed a Kidd trigger on a 10/22 I got for Appleseed this summer...man, that trigger is heaven. I had no idea it would be that good. I had to work hard to avoid the temptation of buying a complete Kidd rifle after all I put into that 10/22...should have got the Kidd rifle in the first place. - typical lesson repeated many times with my gun gear purchases in general.
I was curious to see if you got the trigger installed and your thoughts on it? Thinking of upgrading to the Timney.
Before installing it, I had tested the trigger weight when I first got it. From the Factory the pull weight was 2 lbs 3 oz. It felt a little heavy but not too bad. Installing the spring took less than ten minutes (pull weight now 1 lbs. 3oz just by installing it). It feels 100% better, smoother and light.
With that said, I did get the Timney CZ 457 trigger. Is it worth it? I guess that's an individuals answer. I myself am glad I got it. Simple installation and i have it down to 8 oz. with zero creep. Really like the curve (less then the CZ). The pull is very nice and breaks like glass.
Could I have done that with the CZ trigger - most likely. I got mine directly from Timney with a discount for being a veteran.
Got out to test some SK Match, Long Range Match, Lapua Center-X and Midas +. The Long Range ended up being the obvious winner, with Midas + as the runner up. The Match was a mess and the Center-X was similar to my SK standard results.
Glad to hear looking forward to installing mine this week

Got this in a trade. First CZ. Paint was horrible so I threw some left over stencils on it right over the Manners sponge.
This was the unthreaded version, so we had to fix that.
Got scope and rings, just haven’t got around to mounting it.

Shot mine for the first time today, I’m not impressed. The CZ part is very good, the Boyd part is pure junk. It’s like shooting a 2x4 with a barrel attached. It’s extremely heavy, rougher than a Cobb, two slivers in my fingers already, balance is terrible. The adjustable cheek piece and butt plate, need a pry bar to move, the adjustment buttons barely move. its akin to 7th grade wood shop project, that got a C-. The CZ part is a solid 9 on the 1-10 scale, the stock is a solid 2, on a whole the complete rifle is somewhere between a 5 and a 6. A gun show purchase, you live and you learn. Probably either a candidate for a new stock or life as a safe queen.

I was playing with some SK Rifle Match and Wolf Target Match today at 100 yards with the CZ457 VPT. Range conditions weren’t horrible but the wind was consistent. @ 100yds had to dial .6 mils. For the first target I uploaded I would have to hold an additional .1-.2 mils depending on the gusts. The wind died down for the second which showed a little better result. That said, this rifle shoots like a dream and loves both types of match ammo. Dope was consistent between the two manufacturers. I was only able to shoot two 10 shot groups at 100yds and had to leave, but thought I would share none the less. Shot off of a bipod and rear bag.
Can't wait for the availability of match ammo to come back.
Don’t mind my thumb, I had a misplaced and unwanted 30cal hole on my target so I covered it up.

Does anyone else here have issues with the Anarchy Outdoors 10 round mag extensions? Both of my mags keep jamming up when loaded past 10 rounds. I still leave them installed just for ease to hold onto for reloads, but would be cool to get them working properly.
My AO+3 won't load last round consistently.
Beyond that I am done with AO products. My extension cracked around pin and when contacting them for replacement they insist I return it to my Canadian dealer on the other side of the country. It will cost me $9.45 according to CanadaPost. Not feasble for a product costing $20Cdn. I sent AO detailed pics of damage and they won't honor their warranty and send me a replacment. What does it cost them for a 3D printed piece, well I guess it cost them a customer.
So, instead I remove the extension and ordered an MK Machining 14 round mag. I know they back up their products.
rant over.

Play around with the spring - needs to be set all the way down. that should fix it.

Same issue I had with both of mine. You have to get the spring in there in just right, otherwise it gets bound up wrong. The follower and spring need slid up inside the mag tube together, instead of the follower first and then the spring. I've had zero issues with mine since, including multiple range visits and NRL22 matches.
I'll give it a try again. Every time they stick, I shove a hex wrench in and wiggle it around until the spring sits again, but seems to never stick.
Very lame to hear and also concerning as I'm up in Canada too. I haven't been too impressed with the AOD stuff I've seen so far either, mag extensions aside.
I'm pretty sure I'm done adding stuff to this thing. Maybe. Possibly. I think.
Need some help / advice please. I really like the KRG Whiskey 3 chassis, but its not available for the CZ 457 - not even special order. I intend to by a KRG Bravo for a CZ 457 and a Whiskey 3 for a Remington 700 SA and then swop the backbone and trigger guard to have a Whiskey 3 for a CZ 457. Anybody tried this before or know whether it should work? I can then sell the Bravo as a Remington 700 SA chassis.

Almost finished tinkering with this CZ457. Yo Dave trigger spring or a Timney is next. Has been a blast to shoot at NRL22.

This was KRG reply to my question:
"Hi Paul,
The grips are part of the W3 backend and should fit the 457 just fine. I don’t know about the 700 forend, you will have to try it and see if it works for you.
Thank you,
-KRG"
IMO the forend do not interfere with the magazine - so Whiskey 3 forend should also not be a problem.
