Update: After a long spell of contemplating what to do with my .458 Mannicher Schoenauer regarding a scope fitting, with all the pro`s and cons of what scope base/rings will work, financial input to acquire a set of scope bases/rings which are out of my financial capability, and advice from members not ot scope a .458 Win Mag caliber.....I rejected the idea of fitting a scope on my .458 Mannlicher Schoenauer. I then worked on the next best option, to fit a functional ghost ring...
I went to Johan Greyling ( gunsmith/mentor) to take apart the .458 Mannlicher Schoenauer `s bolt apart and to examine the cocking piece sleeve. I noticed I have extremely few millimeters of metal to drill and tap without altering the cocking piece sleeve and maybe damage it.
Decision:
We decided the best option I have is to make an exact duplication of the cocking piece bolt sleeve mantel ( the en-longed shiny piece of metal usually metal checkered that rides on the cocking piece)
The bolt only from the top:
Notice the piece of metal between the bolt handle and safety. That is what house the safety pin...it is hollow and does not have metal to drill and tap. Dove-tailing the sides of this piece is also not viable.
Bolt sleeve mantel from the top:
This is where I want to attach/soft solder the ghost ring`s base onto.
Cocking piece sleeve from the side:
I have narrowed my search down to a ghost ring sight used on the Marlin type of rifles....
Here is another type of ghost ring I can fit , instead of drill and tap I can use Brownell`s High Force solder to soft solder it as well...
I did converse with a person on another forum whom is extremely knowledgeable in building miniature/scale Mannlicher Schoenauer rifles as a hobby , to get his input and ask him to design an aperture sight for me along these examples I uploaded .
Members , as always your input is more than welcome in this regards...keep in mind the telescope option is redundant...anything in regards to a ghost ring is more than welcome..I am sure you will agree that it is sound advice not to scope this rifle as some of your members had indicated previously...
I am of the opinion that the location of the ghost ring sight will favor my ability to see a better /improved sight picture, since it is near my eyes and a long distance between the ghost ring sight and the front sight/bead. I will remove the island v-express sight ...
