VZ58: Optics, sights & mounts. update sept

Here's fews pics of my final set up on my cz. I put the mounting rail from Interammo, very well made and easy to install, possibly the best rail for side mounting, rock solid too! I made a heavy duty shell deflector with a piece of 14g steel and some flat black paint...may look crude but is built to last! The POSP scope is a very good setup for a CZ, hold zero very well, sturdy and clear image and i like the reticle too.

I asked a few kind members for some tips on mounting posp scopes and figure I should share their responces here, after getting permission. Both are a bit different but might help someone else out as much as they did for me.

Hi,

I've got a few questions of that kind before. ;)

I should probably post the results...

I didn't read the instructions, just common sense and some previous experience.

Installation is fairly simple, does not require going further than field stripping the gun. As long as you can align all the pins and holes, there is not much you can do wrong. Since the aiming mark is not centered, I'd suggest to move it slightly up before figuring out the exact position of the rail (to avoid running out of elevation later).
Install the scope on the rail, clamp the rail to the gun. Here I assume that the irons are zeroed - co-witness the scope and irons at 100m, taking care of the holes, pins, etc. Don't worry about windage, just elevation. Try to position the rail in a way, that minor error in drilling would not interfere with clearance of the pins and serial #. Mark the future hole centers on the receiver.

Drill ONE hole using a bit slightly smaller than the screw - and open it up with round file or any sharp object - just to be able to push the screw through. Keep the hole round.

Install the rail with only 1 screw and check the alignment again BEFORE drilling the second hole.

Proceed with the second hole in the same manner as first.

Remove oil from screws and corresponding threaded hole of the rail with acetone or alcohol. Use locktite on threads and tighten them up GOOD.

That's it. Drill press is practically a must, however the receiver is only about 1.5 mm thick so you can be OK with hand drill and steady hands.

One more thing you'll need later - brass deflector. But it's just a rigid enough shield that attaches itself to the front (small) screws on the rail.

Don't be too afraid about permanent damage, just make it right the first time. It's just a gun...

The setup works great, I shot it at 100 to 500 meters so far. I found that at these distances 1.5-2 MOA groups are average with surplus ammo. Nothing failed so far after about 250 rounds.

I only use the first chevron, don't assume that the next is 200, next 300 - they are NOT!

Let me know if you have any questions.

Cheers,
Alex

Hi, here's fews tips and pics to mount your POSP scope and rail. I will do my best to give clear infos. I dont pretrnd that this manner is the best but worked perfect for me!
# 1 When located properly, the unthreaded hole on the rail should be centered over the sear pin

#2 The rail must be parallel to the receiver as much as possible. Distance between rail and the receiver milled cut is about 0.255 inch. as marked by the red arrows.

distance between the rear of the rail and rear of receiver is about 0.485 inch. Thoses mesurement are only a guide,that's what end up with my installation, to give you an idea.

#3 After you put the rail on the receiver and checking mesurements to be sure the rail is parallel and well located, the rail should be clamped in place so you can mark the location of the rail threaded holes in relation to the receiver. Me i have used an old drill bit that fit in the holes without touching the threads and hit the bit with a hammer to make a mark on the receiver. After removing the rail, the mark left by the bit where clearly visible and then i take a good center punch to mark the holes more deeply for drilling. Before drilling, i suggest you check the distance center to center of your mark and center to center of the rail mounting holes to be sure the distance is the same.

Again when you checked all your mesurements at your satisfaction, you will need a press drill to dril the receiver, with a bit just little larger than the screw so the screws threads wont get stuck in the receiver holes. Also this will give you fews thousands of inch to set the rail properly before tightening the screws. Blue loctite should be use to lock the screws.

The receiver is narrow so i cut the allen key a bit to be able to tight the screw.

Once the rail is bolted the the rifle, just slide the scope on the rail and tighten the locking lever. If you still can move the scope once the lever is locked, you must give more tension. Just slide that little piece so you can remove the lever and reposition to get more tension so the scope mount will lock tighter.

Once you have zeroed your scope, just loosen the 2 silvers screws on each turret and holding the top part so they cant move, turn the lower part with the number until the 0 line up with the mark on the scope body,after retighten the screw securely.

That's it! Its the way i have intalled mine. I hope my explanations will help you.

So glad I went the posp route, pretty decent scope for a very attractive price :)
 
I dont know if this has been covered yet but what rail will I need to co witness my burris fastfire 2 with the sites on my VZ58?

Thanks.....

You can't. The FF is too thick on the bottom portion to co-witness on even the lowest rail (NEA). If you crank the rear sight up to 500m or more you can see them, just.
 
Great, thanks for the information...is it possible to find a pic rail set that has the channel open through the pic rails for me to still use the fastfire? Sorry for all the questions, just dont want to waste cash. Thanks.
 
There are rails with a channel to view the sights through. When you mount the FastFire the mount bolt sits below the top of the rail and blocks at least part of the channel. I've not seen a rail that's tall enough to allow you to see the irons past the mount bolt.

If one was available with a deep enough channel, the view of the irons sights would be very restricted.
 
My CZ-858 is equipped with the latest gen. NEA handguard set. I attached a Bushnell TRS25 and...

It works great! Co-Witness as well! :)

The TRS was on its highest brightness setting for this picture, sorry.

tested it good yesterday and i am really pleased.i have a holosite for it as well..need another cantilever mount:rockOn:
 
Have side mounting POSP scopes gone out of style now? Nothing against other mounts, some of them look fantastic, it's just I like the look of the Russian style side mount on a CZ 858. I've got a POSP scope on the way but haven't be able to find a side rail to mount it on.

Anybody know where someone could acquire one of those Kasat SVD style mounts? I'd love to get my grummy hands on one of those.
