Peep Sight Question

I removed the open rear sight from my HW50s and when looking down into the MT screw holes I see the barrel, I had assumed the barrel and breach block were machined from one piece of steel, I see now that's not the case, I see the seam between the breach block and barrel tube. My question is this, is it ok to leave these screw holes MT and open to the air that may allow moisture from humidity to get between the two or would it be better to close the screw holes in some fashion, like screws or some sort or plug material? I don't see myself reinstalling the rear sight but I still don't want to plug the holes permanently if that can be avoided.
 
This is my hw50 (99) to me in the UK. If nobody makes them on this Forum and I am surprised. Then Join the Airgunforums and ask the question and get somebody to pop one in an envelope and send it to you. Very cheap and a nice neat job. and a very similar Forum to this excellent Forum. Not touting for members just trying to help. :)

I asked a similar question a while back and a member replied that they removed the sight leaf and re-installed the original cover & screws; that's what I eventually did and it works great! :)

BTW, the above hole cover is about as nice a solution as I've seen 👍
Where can we get the above hole covers? That looks nice!

Can you get me some?
 
I have a Beeman/Weihrauch Diopter on my Beeman R9 and Williams on my 30S. I agree that the diopter is the more accurate and I like the proximity to the eye. But the Williams is great on the 30 up to 30 yards or so and it makes for a sweet shooting offhand gun.
I have had three hw30. Nice enough little gun but I think anything the hw30 can do the 50 does better and not that much bigger or heavier. Also full power.
 
I'm feeling down...the Williams peep sight I installed on my HW50S has begun the creep...I can't tighten it enough to stop it without bending the light aluminum base. I will need to find someone with the machinist equipment/ability to drill and tap a stop pin in the sight base. Bummer too, it was cock for dolly on the rifle, I'm back to the less than ideal factory open sights ( for my liking at least ) for now. Just an early morning rant, thanks for taking time to read it...lol

Should not creep. I have had several most on 50s never ever creeps. You can lean on that little screw far more than you think you can. Give it a bit of wellie.:) be sensible about it but if its creeping odds are its not tight enough.

Hints:
1. De-grease all contact points thoroughly.
2. Take out the little grub screws on the side. File or stone flat the ends that contact the body of sight (they have kind of a sharp little ridge on 'em when new). Put a little dry lube (I like lithium grease) on the ends when assembling. This will let you put more tension on them without digging holes in the sight body.
3. Take to heart what the instructions say about going back and forth between the top and side screws. Work slowly and carefully.
4. IMHO, it's no problem if the base of the sight does bow up a tiny bit.

This. I’ve had one on a Diana 34 for 6 months and it hasn’t moved and that gun has a good deal more recoil than our HW50S. I used a toothpick to apply a small bead of Loctite to the rail as recommended by Hector. Let everything sit overnight before putting back together and shooting. Those small Allen screws are used to adjust the width. It’s the top screw that has to be snugged up. Good luck.
 
Better, better for what? The Williams type sits directly above the receiver, the Anschutz/Fwb/ HW types can extend back increasig the sight radius, which makes them inherently a little more accurate. I even have extension tubes on my Anschutz sights and Gehmann adjustable iris's installed, which really help. I also have a Gehmann iris on the WIlliams sight which sits on my old FWB 124d. The Williams is more compact, better for more sporting/hunting as it is less likely to snag on anything. The larger Anschutz or target types are better for target shooting, the adjustmens are probably finer, although am not sure, and generally more repeatable , at least with click adjustable models. I do have a couple of the Anschutz sights where the windeage is by push pull thumbscrews, so not repeatable at all, the click models are very good in that respect. Both types have click adjustable elevation and are easily repeatable.
Curious to know what adapter you used to get the Gehmann rear iris on your Williams.
 
Thanks, for the suggestions, I'll give it another try, I was using the small allen screws to tighten the sight to the rails, That's where the pressure was coming from that was causing the base of the sight to bend. I was using the wrong part of the sight to put the pressure on to hold the sight in position. Makes sense now that I was doing it wrong.

You comments intrigue me…I have no person experience with a 50. I own a 30, 35, and an R9. Sounds like it might be worth adding a 50 in the future.
Very much so but be aware you more than likely will have to do the "fix". If like many owners you strip the gun and give it a bit of a tickle it adds about half an hour to time taken and is very simple to do. Its a fantastic little gun. The .177 is better run at 10.5ftlbs or less and the .22 just a little higher. It is considered in the UK the perfect gun for 12ftlbs. I prefer the .177 and have had, well it must be over 10 not sure. If i need a few Quid for another gun I sell a 99 then later buy another. I am just about to sell one on my Forum in the UK. I had that at 9.5ftlbs. I have had to put it up to 11ftlbs as nobody would I dont think buy it at 9.5ftlbs. People are obsessed with power.:)

A 50 is definitely worth owning.
My list of guns

3 HW30s all 177
1 HW50 177
1 HW95L 177
1 R9SE 20
1 HW95 Field Pro 22
1 HW97KSE 177
1 R1 22

I think that's it.
My favorites by far are the HW30s. BUT if I could only have one it'd be the 177 HW50.

For me it's the best balance of fun, size, weight and power. It's the only one I'll walk into the woods with. I love it's mid size and weight. Shoulders and points beautifully. It has sufficient power and accuracy to effectively dispatch grey squirrels to the end of my practical skills. Approximately 40-45 yards. Although not ideal, at close range, a head shot will put down bigger critters in your garbage pail or trap..

Thank God I can have more than one because I love my 30s. The rest are just fun additions to mix in occasionally.

YMMV
