Rear peep sights

WARNING: I am a big fan of aperture sights...and infamous for long confusing posts about them!

Anyway, on the front sight: I confess I am not familiar with the RX-2, but I assume it has, or will take, the standard Weihrauch interchangeable-insert tunnel sight (which HW has supplied, with the same set of 6 inserts, for their better rifles since the last ice age). The inserts are secured by a rear "sleeve" with a 17mm diameter thread. The bad news is, the insert size and tab pattern are proprietary. They don't fit other brands of guns, and I don't know of any current aftermarket alternatives. Some retailers sell the inserts separately, or you may find 'em used.

Now the good news is, Anschutz front sights fit HW's rails; older ones are easy to find on evil bay and elsewhere. They use a slightly larger 18mm sleeve, and a huge selection of factory front inserts was made (pic is nowhere near a complete set). And there are other options: other makes of gun use the Anschutz insert pattern; Steve Shaver makes a very cool photo-etch insert set for them; and much other aftermarket stuff fits the 18mm thread. One popular and inexpensive option is clear acrylic inserts that give a "floating" ring.

If and when you get a chance could you send me the links to the three that you mentioned because I only seen the FP-AG
Here is the link to Williams's site:

The FP sights we are discussing have the adjustable base for airgun grooved scope rails, as you see above.

AG stands for "airgun." These sights have a short base that sits relatively high. Intended for barrel-cocking airguns with some barrel droop (which tilts the line-of-sight up above the receiver axis a little).

GR stands for "grooved." Intended for .22 rimfires with no barrel droop, but works for some airguns as well. They have a longer base and will adjust a little lower.

TK stands for "target knobs." These are optional knurled finger knobs, to replace the flush slotted elevation and windage adjuster screws standard on the FP sights. (Thus: low sight with flush adjusters = "FP-GR;" B-o-G's pics above are the high sight with finger knobs = "FP-AG TK." Whew...)

The 5D sights are a simpler, cheaper line that have screw-secured, trial-and-error sliding adjustments, no click mechanism. They also come in high (5D-AG) and low (5D-GR) versions for grooved rails, but obviously there is no target knob option.

I have one of the earlier Williams 11mm dovetail sights (got it from Beeman back in late 1975 early 76). It is specifically made for the 11mm rails and not adjustable for rail width like the current models. It is mounted on my FWB 124 and has never moved.
Cool! I have two similar old ones that were made for the pre-1980's HW 13mm rails.
 

My guess is the AG would work best on your gun, but check with Williams. I just put one on a Diana 34 and looks like it will be perfect. Trying it out a little later today. I don’t know a lot about your rifle, but if the front sight is screwed on there are lots of options for replacing.
The front sight post slides into the globe which then slides onto a dovetail that's cut into the top of the barrel by the muzzle.

The top picture is what I have on my rx2 meaning the front globe site and inserts but ask for the inserts I only have a rectangle The hollow circle and the tapered rectangle. I am hoping to find one day a lollipop one that I see up there. And in the bottom picture is that the anschutz you were referring to?
 
So what were the ones that you suggested again? Also I was wondering

What are the ones that you suggested to get again? And I was wondering do you think that the target knob version would easily be caught on your hand or sleeve of your shirt or be in the way whatsoever when cocking the gun or using it in the field? Lastly if I would like in my opinion I would like to have the Target now version. But I'm wondering do you have to buy the regular version then buy the Target knobs to place into the regular version and replace the old knobs or does it come already pre-made with the target knobs already in and ready to go?
 
Anyone recognize this Weihrauch diopter? 13mm How many different models did Weihrauch make?View attachment 290720
That's an early version, before about mid 50's but Mike D will know for sure. The thumb screw fixing the windage adjustment is missing, I think, but again the expert will know. It seems a close copy of the very hard-to-find Falke 80/90 rear sight???
 
AG is for guns with high line of sight and GR for low. Look at how they sit differently on the mount/base and you can see how they sit differently on the rifle. MDriskill has a ton of experience with peep sights and BoG as well. If my opinion differs from theirs, go with theirs LOL. I got to put about 40 shots through my Diana 34 with newly installed FP-AG-TK before weather ruined the party. Very happy with it. Again, contact Williams and ask which they’d recommend for your gun.
 
I forgot to mention earlier, I found a Gehman adjustable iris for the Williams sight.

pricy but worth it. Thread is 7/32 x 40 for Parker Hale, Redfield, Lyman and Williams.

Wow nice find!!! Ordering one now! 👊

If you buy the TK version the target knobs are already installed. Just install on your gun and sight it in. I didn’t have any issues with cocking or anything else. The target knobs have a set screw and shouldn’t move unless you loosen the screw.

That Gehmann iris is really nice but costs a bit. The Williams peep comes with a 0.095 aperture. A 0.05 and a twilight aperture are also available. Not as nice as the Gehmann but you can get the pair for 25% of the cost. The sight ChuckHunter just posted looks like an AG-TK with twilight insert installed.

Yes, the Gehmann iris is pricy, but nice and convenient. I think mine adjusts from 0.5 to 3mm so I can adjust for varying light conditions with just a quick turn, beats carrying other apertures around. Downside is it looks big and bulky.

Those little Williams sights are a lot nicer looking than the big Anschutz and Feinwerkbau sights on some of my other rifles. I have it in more of a sporter application, and even with the target knobs it looks sleeker and trimmer than the other sights. I have really not tried it for repeatability of adjustments. I have never had a problem with the target knobs catching on anything. I got mine with the target knobs as said last two letters of model number is TK.

BELOW IS STOLEN FROM A POST I RECENTLY DID ON ANOTHER SITE. YOUR OLD ONE IS THE SAME AS THE ONE IN THE MIDDLE OF THE PHOTO, BUT AS NOTED IS MISSING THE WINDAGE LOCK. PROBABLY MADE 1956-ISH, GIVE OR TAKE.

THESE OLDEST HW UNITS HAVE A DOVETAIL OF ABOUT 12.5MM. THEY DO NOT FIT EITHER THE "13MM" GUNS FROM THE 60'S AND 70'S, OR THE "11MM" ONES MADE SINCE.

These three diopters are from HW 55's. The two on the left are older, and solid milled steel. This "turret" style must have been manufactured in small batches, as there seem to be endless variations in them. The third one on the right is a newer generation introduced about 1959. Points of interest:

1. Huge eye disk with textured anti-glare rear face on this early turret sub-variant.
2. The disk's front flange mates with the turret's flat rear face, to lock the elevation adjustment into place.
3. The only function of the huge thumbwheel underneath is to lock the windage setting (do Germans obsess over wandering settings?)
4. On this later turret model, the top thumbwheel, which mates with the positioning holes in the rifle's receiver, is recessed to fit flush with the base (on the earlier sight to the left, it just sits on top of the base). The whole rear section is also dropped down a bit.
5. This later revised sight design has changed to a more elaborate cast-metal adjuster module.
6. But the base is still solid steel. As far as I can tell, the small tapered radius down the top edges is purely for aesthetic purposes.

Note that you can also get a simple adapter bushing that has male US thread at the front, and female German thread at the back. This allows you to buy just ONE German-thread iris, and use it on just about any sight you will ever own.
