How big is the hole if you screw out the whole aperture? Ghost-ring like?
Hi Caberslash,
The aperture I have is larger than the one pictured and be bigger again if removed

Hi Folks,
I am currently looking at putting a set of iron sights on my CZ452.
Getting a rear peep isn't difficult, there are Skinner sights that fit the dovetail or onto a Pic / Weaver rail, the issue is front sight and front sight height as rifle doesn't have front sight ramp or dovetail slot.
So, question is: what size ramp and what size front sight blade? Tough question as if you fit the wrong ramp you won't get a blade that works. I asked the folks at Skinner this question and they came back with:
"The Shorty Ramp is a super choice, with so many dovetailed front sights to choose from.
It sounds laughable, but cinching a black zip tie to that barrel with the tail bent/oriented sticking straight up to use as a front sight will tell you how high overall a front sight/ramp combination needs to be to zero with our rear sight.
Just keep clipping a bit more off the top end with nippers in between shootings until your elevation is correct/zeroed, then measure the height from top of the barrel arc to the top end of the zip tie. Fine tuning can be done with the rear sight once the new ramp/front combo is in place and correct within .025” or so.
Most dovetailed front sights look best between .350-.400” to about .500” when in a ramp, so knowing the overall height will tell you which height ramp will match up with a .350- .500” front sight to be correct overall.
Shooting @ 25-50 meters is best.
Thank You for checking in!

It aint dumb if it works. I shall try it and report back.

Well folks, with the above, a cable tie with a rear NEGC peep got me a just over inch group at 50 yds. So gets me a working height for a ramp… so, plotting restarts![]()
I do have one of those NEGC sights:

It might get pressed into service. Must admit though, it is chunkier than you might think.

The hole when the insert is removed is a bit over 5mm but not totally round (behind the threaded portion are 2 verticals inside the sight) which make the hole not quite round which I understand isn't idealHi Caberslash,

Just as an FYI, the aperture I have in mine seems bigger than pictured above, maybe a bit over 3mm diameter.

Pleasure. Anything else I can help with, please let me knowThanks very much for the pic.

I have a skinner on my .357I'm currently thinking about putting iron sights back on a Brno / CZ .22 lr
Something like a Skinner Rear Peep:

And a Williams Ramp for the front:

Something worth thinging about - if you can get a front sight ramp that takes 3/8" dovetail front sight posts as they are the most ubiquitous.
Something I think I will do though is make sure the ramp sits a bit back from the muzzle threading shoulder as mods tend not to sit sharply flush with that line and might not fit quite straight.

Was wondering if anybody knows of a peep/ghost sights that fits the Tikka rail?
I was considering machining the rail on a Tikka to fit a Talley peep sight... but if there is already an option out there
If you can find out the rail measurements, have a look at Skinner:Was wondering if anybody knows of a peep/ghost sights that fits the Tikka rail?
