CZ-452 elevation adjustment.

[stockranger]

Stockranger is saying that I can zero at 25, and that I'll be dead on at other distances so as long as I raise the rear sight. (At least that's what I understood).

And Izzy, you said this





Sorry.

Izzy is explaining the trajectorys IF YOU DO NOT SLIDE THE REAR TANGENT SIGHT FOR THE DISTANCE. His trajectory is correct.

I explained it assuming you are going to slide the rear sight for each distance. The rear sight is calibrated from the factory to the typical HV trajectory. Just slide it and it moves up and down allowing you to be dead on from 12.5 to 250 meters.What izzy explained is engineered into the rear sight and it makes it the best factory sight on the market.

If you haven't memorized .22lr trajectory you should. It will help you be a better shot. Learn the SS and HV trajectory so you can estimate how it will differ from the factory calibration when shooting different kinds of ammo. Sometimes when hunting there may be no time to adjust the sight if the rabbit is running so you need to know the charts. I adjust it for every shot when I slowly stalk sitting rabbits and it works great if there is time. If you don't hunt then you will always have time to set it to the right distance.

Thanks, that was what I was trying to explain but I guess I wasn't clear enough. Sorry for confusing anyone about the trajectory issue.

[rojocorsa]

Oh, OK. I get it know. Thanks!



It makes me feel even better about my purchase. People keep telling me that the sights were excellent, but I didn't necessarily understand why. So an iron sight zero at 25 it is.

Thanks guys!

Check out JnP gunsprings for the ghost sight. It will take the place of the rear sight blade as I showed you in the photo. All you have to do is center the tip of the post in the circle Your eye will quickly and naturaly center it up. If your sight picture is like the photo the shot would of gone a tad low as the tip of the post is just below the center.

You can read more about it on rimfirecentral.com

When I fist got the rifle, I shot it poorly. Of course, I didn't even have a feel of how the sights worked. Given that my sight is low on the ramp making it short, it shoots high at 50. The first time I shot the gun I wasn't even on target because I had the rear sight at 50m in addition to that low front sight.

Man, I really feel like I've come a long way....



BTW, what size allen wrench do I need to loosen the capture screw for the FS? I never found out.

I wish you were local so I could just meet you at the range and help you in person.

As for what size allen wrench, I haven't a clue. I guess my model is older since my front sight capture screw is held on by a slotted screw so I just used a very thin flat-head screw tip from my gunsmithing screwdriver set. I bought mine in 2003 BTW. And don't worry too much about how high or low the front sight sits in the slot - all that matters is that the rifle is zeroed for the ammo you will be using.

Also, your CZ IS a great rifle and don't let anyone tell you otherwise.

[rojocorsa]

Thanks Beetle.




(If anyone else knows what size wrench I need, please let me know so I can go buy it and zero my rifle).

Thank You.

I've been looking at my front sight screw...I'm going to take a guess that it is 0.5mm?

• If you haven't pulled the hood off yet be careful doing it. You have to spread it a little and pull it forward, but make sure you PULL it forward, don't push it. The front sight blade is hooked back and will tear a nice deep hole out of your hand or thumb.
• Buy a set of small metric allen wrenches, it's not worth buying the wrong one once. I don't know the size.
• Get the ghost ring right away, it's fantastic.
• Here is a slideshow I made for disassembling the bolt on the 452.
• I use JDewy .17 rods (the .22 is too tight) with .22LR over-sized patches and .223 brush with adapter.
• I lowered the trigger creep by rolling a strip of copper sheet around the trigger pin and soldering it closed. This had the benefit of not having to drive the pin out and back in but I felt was stronger than using aluminum tape. Fuzzy Limey Trigger Modification.
• I shoot aguila super extra 40gr high velocity simply because it's good and cheapish. If I could find the generic cheap American Eagle ammo I'd shoot that. Originally I shot the AE ammo and it surprisingly shot very well.



I love mine. Light and cheerful gun, shoots very well offhand. Spent the day yesterday shooting at a 4" steel plate at 100yards and was hitting it 80% of the time offhand.

[rojocorsa]

Thanks. It does feel nice offhand.


I went by the hardware store today. Since I'm cheap and I'd rather spend money on bullets, I only picked out one tiny little wrench--a 1.5mm hex. It worked. For anyone that cares, I guess the size of the hex screw is officially 1.5mm. I got lucky.


Never seen that Aguila stuff, but it sure looks better than that Super X and CCI Blazer blazer I have. I do favor the Blazer over the Super X. I felt like it shot better through my rifle. I think I'm just going to hold on to that RWS R-50 stuff for whenever I get a scope.


My first serious upgrade will be some real sling swivels, so that I can use my USGI sling.

[milotrain]

Next time I order anything from midway I'm going to get a brick of the Federal AE ammo. $23 for 500, and while they are not match grade they shoot quite well in the CZ (YMMV).

also GHOST RING You'll kick yourself for not getting it earlier whenever you end up getting it.

[rojocorsa]

I just ordered my pair of sling swivels. I hope they ship without incident.

OK, I'll bite. Please tell me more about those ghost ring sights.

Thanks.

[stockranger]

Your typical uncle mikes QD swivels or similar are not going to fit unless you drill out the holes a little bit. It is no big deal. Just remove factory swivel. Carefully put gun in a vice and slowly enlarge the hole in the stud with consecutively larger drill bits. This was the first thing I did when I got mine. A set of swivels from walmart is th emost cost effective thing to get.

The ghost ring sight will be shipped to your door for like 20 bucks. I suggest the largest size as smaller sizes could cause eye strain. It installs with a small screw driver in place of the factory blade. THe advantage is your eye will naturaly center the post inside the ghost ring. If you don't like it then someone should buy it for 15 bucks shippes no problem.

While you are already paying shipping you might aswell get an increased power striker spring from them too. It'll really make your groups more consistent and also very cheap easy upgrade.

I still recomend some winchester subsonic HP. THey have it at basspro in rancho or on their website. It is 30 dollars for 500 rounds. I think you will find it much more accurate then what you have been shooting, especialy past 50 yards. Not to mention it is about as loud as a pellet gun out of the lux which is really nice.

rojocorsa, I'll buy it from you if you don't like it. I have the largest and want to try opening it up a little more. I was concerned, having never shot a ghost ring before, weather I would be comfortable shooting with it. In a day of shooting I was better with it than my old blade. I tend to use a 6 o'clock hold with a ghost ring for some reason.

I bought my ghost ring from eric brooks a long time ago, thanks for the link to J&N. Didn't know people were still making parts for them

++ on subsonic. I've had better accuracy with subsonic but I can't find it cheap near me.

.

I was also interested in an even larger ghost ring. I still have a ton of accuracy and I think a little bigger would allow faster target aquisition hunting in low light. I have been thinkin of asking JNP if they could make me a larger one. I have read before about them making a guy a custom size.

[milotrain]

Well maybe I'll make a few then
