Factory CZ457 to competition ready | What upgrades increase accuracy? (2023)



Well, Howdy Folks, thanks for joining the Eagles Nest.

Now, I got a very interesting video.

Something I think you guys will actually really enjoy.

And we are basically going to be taking out a brand new out of the box.

Cz 457.

This is a synthetic stock model.

The very base model about 500 bucks is what I paid for.


This CZ 457 like I said, is bone stock.

The only thing that I did on this is put a area 419, 40 MOA rail as well as a bolt knob.

But the question I've always asked is what upgrades actually make a difference for your Precision Rimfire rifle so we're going to take the bone stock CZ 457 out of the box at 50 yards, shooting SK, a rifle match as well as ele 10x and then we're going to go ahead and drop it into an ACC chassis.

Now, this is a pretty much a pretty expensive upgrade looking at a chassis cost around a thousand one hundred bucks and we'll see what that does as far as accuracy we're.

Then also going to test maybe The Simple Solution will be a tuner.

Now, this is a EC tuner version.

One we'll, go ahead and install it on the factory barrel and see if we can get that thing tuned in what kind of performance.

We could get we're also going to go ahead and try out a suppressor.

So I get a lot of comments.

A lot of emails for requesting suppressor use on a Precision Rimfire rifle it's been my experience that a suppressor actually will hurt accuracy in the long run, but we'll give it a test today.

So I have a thunder, Beast arms takedown 22 that will go ahead and install on the factory Barrel as well.

And then the last thing we're going to install is going to be a brand new Barrel.

This Barrel is a heavy Contour.

It is a Douglas 1 in 14 twist.

This is my notchless Barrel.

So you guys can see there's, no grub, screw relief.

Cuts chambered with a jgs match chamber 24 inch length double recessed Crown.

So it is not threaded.

So like I said, Fresh, Off, The, lathe, we'll, see what kind of performance.

We get we're just swapping a barrel into the chassis into the CZ 457 and see if that upgrades the performance downrange as well.

So you guys will like this one stick around we'll get to it all right.

So before we do anything we're going to make sure the grub screws are actually torqued down 35 inch pounds.

So we'll make this a fair test.

So I took the barrel to action off, um out of the synthetic Factory stock.

And we are going to go ahead and torque.

These things down exactly 35 inch pounds using a borka tool kit that I have here.

So I believe, this is a factory, 20 inch barrel, a very skinny Contour, super super thin, but they still have it threaded half by 28.

So good job CZ on that one.

So let's, go ahead and get this thing to torque down and we'll get it back into the stock all right.

So I just finished up actually zorring out the scope, the scope that I am using is a validata G2 Mini.

Now, this is a new offering very awesome little, scope that I'm finding out to be 34 millimeter tube, Val data rings.

And it sits on top of the area, 419, 30 MOA base with the Aero 409 bolt knob Factory configuration, shooting SK rifle match, 50 yards, let's, see what she does.

Oh, one other thing we're shooting off a bag.

So my dumbass forgot, they bring a bipod today.

So we're gonna go old school and shoot off a bag.

Hopefully I can hold a group let's start off with the center.

Here I'll point it out on the video eyebrow mag is all I got so let's, see if I can hold the group here I got a cold bore shift for sure, um now, these aren't the best range conditions, but we are going to do what we can do all right, let's, Loop.

Another, five more and let's see if that improves all right let's go over to the line on the right there and shoot another five shots here at the SK rifle.

And these are I feel pretty solid I think, uh, it's, just not like it does ammo.

Oh it just stacked three in the same hole and we're having a cold boar shift for sure all right it's coming together.

We'll shoot we'll, go ahead and shoot another.

Five more.

It seems like this Barrel is, um showing to be pretty damn accurate with the SK rifle.

Hi let's.

See if the other two follow, yeah, there's, definitely a cold war shift.

So you could definitely see at the pattern it's about the same.

Yep, foreign on that one one more all right so looks like it's, definitely over MOA.

That was three five shot.

Groups, Factory configuration.

Let's, go ahead and throw the suppressor on and see what that does.

So one thing about thunderbeast arms, they recommend a 0.430 10 in length for the thread.

I can definitely tell that is a lot larger than 0.430, but let's, go ahead and load up.

Five more see what kind of uh, Port of impact chip we have.

And if the groups do improve that's, uh, one of the things I've always wondered, you know, I heard a lot of folks talk about suppressors improving groups.

One thing about a suppressor like I mentioned on my 22 long, rifle accuracy series is that it actually starts collecting the lead debris, carbon debris and all that which entails more weight.

So it starts to collecting more weight and essentially becomes a D tuner.

So to say, but we'll, go ahead.

We'll aim, just right at that last five shot group and see if it shoots lower higher or whatnot, uh, all right.

Top left.


Okay, looks like the cold bore shift is a minimize a little bit.


Groups are definitely improved.

So far.

Interesting, everything's, quiet, huh, all right all right so I'd.

Let the barrel cool down at least 15 minutes and we'll.

Go ahead and see if there's is a cold bore shift now.

So we'll aim just right of our last Target here.

This target cam is a huge help.

Finally was a ble to get one for myself all right.

So no cold war shift interesting.

Well, maybe I spoke too soon all right.

So it's obvious that the suppressor significantly improved the group size I'd say, with that, one outlier on the right, we'll, go ahead and shoot another five shots, just to confirm that wasn't, just the ammo or me, almost zeroed out, yep, foreign that's, crazy, how much this suppressor made a big difference? One more here.


So even with the weather we have going on this thing is, uh, this thing's, a shooter with the suppressor.

Now one thing like I said, even though this is shooting very well.

This suppressor is clean there's, nothing in it so far, besides the last what 25 30 rounds.

So we don't monitor the weight.

This thing this thing could possibly start collecting a lot of debris and whatnot.

Another thing that folks are not really aware of or are just learning a suppressor with collecting all that debris on a competition setting.

We typically start with the rifle pointed up.

So when you do that all that carbon and debris starts flowing down down the bore, and that could cause your first round shot to be off.

So let me simulate that see if maybe we'll have a flyer we'll shoot at the same group there so let's see what that's that does I, definitely, yeah.

The bolt itself felt gritty as hell.

So it definitely threw a bunch of debris down the bore Let's, uh, let's, see what this thing does? Yep, so, yeah, you can see right? There, that's, uh, that's, a disadvantage of a suppressor and that legitly, um, threw a flyer.

Just just haven't had debris down the bore, and you could definitely feel it all up in the bolt.

So actually let me show you guys real quick.

Yep, you can see it all around the bolt head here.

So one of the disadvantages of shooting suppressed on the 22 for sure all right.

So I, went ahead and installed the EC tuner version one on the CZ.

And instead of boring, you guys with all the tuning and showing all the shots down range.

What I'm going to do is just fast forward the clip on this video, shooting two to three shot groups and getting this thing tuned in and I'll tell you exactly where this thing landed.

So let me go ahead and get this thing tuned in we're going to start with zero and pretty much work out two to three shot groups, we'll, see if I get this thing as accurate as I possibly can with the EC tuner foreign all right? I think, that's the setting right there all right.

So that didn't take me long at all.

It actually took me about 10 shots.

So the EC tuner definitely helped, um, I, definitely, uh.

All I did was basically shoot five shots at zero on the setting went up to five and shot.

Another fire shot group.

And that thing just started attack driving.

So the factory barrel with the EC tuner.

It works.

It works very well and Tuners could definitely help out.

But that doesn't show you the accuracy potential of a rifle we're only at 50 yards, um, so I'm, kind of a little curious, um I've been recommended SK pistol match this one is a pistol match special.

So it should be the same lubricant shouldn't have to foul the barrel with the barrel tuned as it is I, didn't, touch anything at all with EC tuner let's.

Go ahead and throw five shots, just right of the last group and see if we can get this thing to shoot good as well with the SK pistol match special I, got no clue where that thing went.

Okay, way the hell up there all right.

Good thing for the Target cam foreign kind of all over the place with SK pistol match.


Last shot here.

So the question now is does a tuner help this situation out? And the answer is actually, no, um like I've seen a lot of YouTube channels.

You know, recently playing around with the EC version 2, tuner that just doesn't seem to grasp the concept that you actually need to find the ammo that shoots well out of the rifle first, or at least do some lot testing from a different rifle.

Uh, this SK rifle match that I have here has been lot tested from my own.

You know, experiment, basically.

And this thing has absolutely shot lights out with pretty much all of my rifle builds.

So I know that this [ __ ] is at least consistent enough to produce the groups that you're seeing today.

So again, if you're going to play around with a tuner, the concept is finding the ammo that is consistent enough to produce match great accuracy.

And then the tuner will help fine-tune that as you can see, you can't go out there, throwing whatever ammunition you find off the shelf and expect a tuner to do Miracles, that's, absolutely the wrong way of doing things and you're, just wasting your freaking time along with doing videos on doing what you're doing you're just you're, not doing it right it's going to be straight up on that.

So with that said, we'll, go ahead and remove this build action off the factory stock throw into the ACC stock chassis and let's see if the groups get any better than what it is.

I mean, honestly the way it's performing with the EC tuner with the factory Barrel, it'd be kind of hard to justify this thing, needing any kind of upgrades to be honest, but that's just my experience so far all right let's get to it all right? Folks.

So I have the MDT ACC chassis.

This is actually from a good friend of mine that I'm actually re-barreling his CZ at the moment to borrow this for the video with that said, we went ahead and loaded up SK rifle match the same ammunition.

The tuner is set exactly what it was I.

Didn't do anything to the tuner at all so we're going to keep it as is will shoot a five shot group may need to refile the barrel, but we'll see that is close to that Target can Let's, uh, I'll risk it for the biscuit here, no cold bore shift.

The best benefit I can tell you right now with this ACC chassis ergonomics is a huge upgrade got my cheek.

Well, planted very tight, I feel solid thumb rest, where I want it right hand.


This is one of the best upgrades for a chassis for this system here or this type of rifle.

You see there that's shooting lights out already it's, even with the wind conditions.

We have here are all touching all right.

So that's bug, holding Factory Barrel, basically, nothing.

But EC tuner ACC.

Chassis did the groups improve looks like it did very slightly.

It could be just the fact that I'm, not, you know, floating my cheek.

Weld I got a more solid system here, um, the ACC chassis, obviously doing his job.

And it is shooting lights out.

No joke this, uh, the CZ is Factory shooting lights out as it is.

Now the downside to this whole system with that skinny ass Barrel is they uh, the balance of the rifle.

It is definitely ass heavy it's, uh, gonna need a lot of weight in order to get this thing balanced out if you're going to consider this setup for a PRS or interroll 22 setup.

So that will be the downside to having a barrel like that.

But we'll go ahead a little five more and let's.

Go get this scope adjusted and let's see if it will hold another group.

One thing like I said, is zero, Cold, War shift.

So this is one of the better barrels for hot, perhaps that I've seen out of a CZ that are shooting very well, right out of the gate.

I hit low weird get a little bit of horizontal string in that's, uh, it's.

Odd, let's.

Go ahead and uh, let's try five more I.


Think that was me, but never know tight.

Scope adjustment let's.

Go get another box here foreign kind of walking up on you.

But still a pretty good group.

Foreign see that last shot was almost the same hole, pretty much the same hole well, but I could say that that could contribute to me shooting, uh, SK pistol match is definitely coming together.

And this thing is loving the EC tuner in the setup.

So the question is, what does a custom Barrel do for you let's? Get that installed all right so got the new Barrel installed into the CZ action? The cool factor is definitely there.

This thing does feel a hell of a lot more balanced, uh, it still is ass heavy.

If you guys are close up here, this build action definitely does fill the chassis very nice could have been a little bit bigger on the barrel, but that's, just the Douglas Barrel profile that uh, I got spun up.

Um, I did ask for a 1.1, but got a one inch, which is all right thing is still they'll.

Still should shoot pretty good, hopefully, but we'll see.

So this is a 24 inch barrel.

This will be four inches longer than the factory Barrel as perspective.

Here 's the factory Barrel with the tuner.

Obviously so it's, roughly about, uh, let's say, two two to three inches longer and uh, we'll see what SK ruffle does first rounds out of this Barrel it's got a pretty high bar set.

So I think my custom Barrel is going to be sweating some bricks right now.

Target cam died on me.

Yeah, it's all right.


Go ahead and shoot a group we'll, just shoot next to the last one and uh, I'll, walk.

You guys up there, chamber's, definitely tighter.

You feel it when you uh chamber around here, I'm, hoping that didn't hit my damn tripod, all right, let's, uh, I mean, I'm on the right here, see where this thing's going you? See? Another? Huh? Yeah.

I'm just seeing more.

Yeah, I can see it? Oh, okay.

I see it.

Oh, let me just do a group on this one and see exactly where it's at foreign point of impact all right.

So that was 15 shots, Fresh, Off, The, lathe, brand, new, Barrel, let's, go ahead and walk.

You guys down there.

So those groups were the first five right here.

Fresh Off, The, lathe, I was aiming like right here and I saw it hit way over here.

So I got the scope adjusted just correctly.

Next five shots I had one drop low for some reason.

This was the flyer that I was noticing, but all four of them stacked right here in this same hole.

Next five shots, right here and that's, just from the barrel comparing this to some of the other.

Um groups here you can see that there is a slight Improvement in the group with that Barrel seems to be a little bit more consistent as far as the group size, um, we'll, go ahead and try some Elite 10x now all right.

So this Barrel is acting like it.

Absolutely hates Ely.

That was the first five shots on the elite 10x here.

And his Jess was not doing good.

It actually was like nope, but like that another five shots doesn't like that another five shots here.

And it started to come together.

So I was like, you know what let me get this thing.

A chance did another five shots.

And there was three stacking.

And then we had two outliers for some reason and the last five, um, definitely still competitive.

But I'd say, I'm, not not in my standard I'd say, that's, uh, needs a little bit Improvement.

But overall, if you take a look at the groups of the new Barrel, um, the custom Barrel did for the CZ.

It does seem to be a lot more consistent versus, you know, the shooting suppressed or shooting with a tuner, I mean that Barrel didn't need anything other than just throwing a barrel on there as done correctly, correct headspace, good chamber.

Good Barrel.

You can see that it's it's pretty much favoring SK, ammo, um every barrel kind of has its own little niche.

But it does shoot SK, very consistent we're, pretty much saying that that's that's pretty consistent loves SK pistol match special that's.

Basically, I think a sub two inch group.

Go ahead and measure that.

But overall that Barrel that's, easy 457 is definitely competitive worthy now I'd say that this does keep up with a lot of my custom rifle builds.

So we'll, go ahead and shoot the rim X.

And we are losing a little bit daylight.

So let me get this done real quick I'll show you the groups off the rim, X and we'll.

Compare the complete done up CZ 457, fully upgraded outfitted with a new Barrel ACC chassis What DOT, compared to a custom rifle complete build rimx.

All right.

So I am losing daylight.

Let me show you guys the groups on the rimax.

So the rimax is definitely not picky.

And let me explain what's going on here.

So the first five shots was SK Rifle, right here.

Um did another five shots.

Right here.

You can see that thing is tack driving switched over to SK pistol, special match five shots here, didn't, really like it as much.

And then another five shots here.

I, then went ahead and shot, Elite, 10x and there's actually, five shots right there, uh, next five right there.

And then the last five right there, well, folks it's safe to say that the rimx rifle does offer a little bit of advantage and what I mean by a little bit of advantage that's.

My opinion, obviously is that the ergonomics are are very awesome, smooth action, um, the benefit with having a nice bull barrel like that a 120 straight Contour and a huge rigid action.

The way it is it offers basically the rifle to be less.

Picky, downrange, that's been my experience so far now, the CZ fully outfitted is obviously going to be cheaper, not much cheaper to be honest, but still cheaper, and it definitely will keep up with the Remax rifle.

But it is a little bit more picky.

So the moral of this whole story and moral of this video.

Basically, the purpose of it is basically the Showcase that the rifle is only half the battle I said, this a lot of times in my videos, the ammo makes a huge difference.

And some out some rifles are pickier than others.

Some rifles will outshoot other rifles, obviously, but what I consider a accurate rifle is something that you could take out to the range and just throw whatever you want at it, throw Elite, 10x, SK, rifle match, perhaps elite team.

You know, anything of the cheaper stuff, even the SK pistol and go out there and compete, competitively, well, that's the results for today's testing guys, let me know what you think comment below weather conditions weren't the best.

But you know, what did shoot pretty well even off the bag in my opinion, comment below guys, let me know what you guys think and thanks for watching I catch you guys on the next video.
