Title: OEM 2300S Muzzle/Post Sight Modification
Post by: Drdan on December 24, 2023, 04:12:15 AM
The Lothar Walther barrel on the 3200S has a flattened area on the distal part of the barrel.  The OEM muzzle/post sight has a set screw on the posterior aspect of the barrel as seen in the image.  Move the sight post proximally, and place the set screw on the anterior of the barrel.  It would now be able to be set in the same position should you remove the component. The end result would allow you to shoot with the Williams sight, and with the Williams off you could co witness the scope or red dot with the post sight.

I don't think I am allowed to modify the LW barrel to accept a 1/2" X 20 muzzle brake, so this modification would leave the barrel intact, allow the OEM muzzle/sight post to be utilized, and facilitate co witnessing...   8)

The threaded adapter is from this French site, right?

Yes.  They are not in stock.  If the machinist can use the OEM muzzle, some fluting can be saved.  Do you know if the OEM muzzle is aluminum or stainless steel?

It's anodized aluminum.

My CCS 2400KT in the US came with one, but I never used it.

I think I still have it if I haven't donated it already  :-\

A friend here in Germany advised me not to modify the LW barrel.  I thought of the idea to modify the OEM muzzle, which would not be a difficult job whatsoever.
The French company's offering looks very nicely machined, and it probably made of steel.  I don't usually settle for second best, so I just sent them a very friendly
e-mail inquiring when they will have the adapter again in stock.  I already have a muzzle brake adapter that is a "slip on", but fitting it necessitates the removal of the
OEM unit...

Being that I will be finishing parts with several PVD TiN colors, Teur Meen in Holland can mirror finish them so they should not show surface flaws.  I have an aluminum
trigger cover, adjustable sear, a roller trigger, and a red dot mount on the way.  I'll be ordering brass tube caps, a stainless breech cap, a brass safety, a stainless steel
extended probe, and brass grip screws, preferably Torx or Allen head. 

Here in Germany the weather is similar to the Northeast U.S.  I'll keep my 2300S in an aluminum pistol case with a container of color change silica gel to keep any oxidation
at bay.   :)

Yes, don't do anything to your barrel.

It's pretty thin to be directly threaded.

The only mod I did to my Crosman LW barrels was to deburr and polish the leade.

My 10" 17xx LW barrel was not very accurate prior to the method.

Whilst chambering the pellet, I would feel the grittiness, especially with H & Ns which is a brand with more antimony compared to JSBs.

Is the LW nicely crowned?  I am asking my guy to deurr the barrel and clean and mirror polish it internally, as well of course externally.  Same for the breech, especially for the throat area.  I don't really think that my specialist needs any coaching as he let me know that polishing is a specialty of his.

If you are really wanting a front sight there's a way to do it.

It would be a sleeve behind your threaded adapter.

I'll post a photo in a while.

They are, but my 17xx also had an infinitesimal burr, so I recrowned it.

Somewhat like this but thicker.

I am pertaining to the stainless piece behind the pickle adapter:

It is my 24" .177 Crosman barrel in the PI which is uncannily accurate.

I paired it with a 6-24x40 Bushnell Elite AO mildot scope which is almost 2' long with a sunshade  :-\

Assuming the LW barrel is 7/16" like the Crosman barrels, they are easily threaded.

I have threaded them 3/8"x24 tpi and 7/16"x20 tpi   --   both in .22 caliber   --   .177 would, of course, leave more metal.

Hi CraigH. It might not be legal to tamper with the OEM barrel that comes with a specific model, so I will use a "slide on" adapter like all the German air pistols and rifles use.  I know that you can't install longer barrels.  It would be nice if airgun laws were much more iberal like they are in most states in the U.S.  :-*

That is a fascinating situation (tamper with an OEM barrel).   And yet, as I understand it, moderators are legal (on airguns and firearms) without permit in Europe.   Unlike in the US where a tax stamp ($$) and waiting for BATF to run a background check are required.

I bring up the last sentence, since while airgun moderator ownership has been adjudicated, issues still come up on occasion.

The main thing here (USA) is (should be) do not make the devices with 1/2"x28tpi threads.    I define "devices" as moderators and adapters.   And while staying within these bounds, occasionally one hears of the BATF expressing that if an airgun-legal moderator were to be adapted with airgun-legal threading to a firearm and function (to destruction) only once it is an illegal act.

Apologies if this is a bit "in the weeds", since none of us do such things.  And I state this with sincerity, not with any effort to be cute.

Merry Christmas Eve!
