Re: .458 Mannlicher Schoenauer

Good day members
This is where I am currently with the .458 Mannlicher Schoenauer`s ghost ring build. After a lot of deliberations, research, options and design issues looking from every angle to this setup and what will work best I decided to take this route. Keep in mind the Lyman ghost rings are just too expensive when purchasing in South African Rand currency. I did look at all possible known designs and did not see a workable option other than drill/tap and soldering a ghost ring to the cocking sleeve surface.

As usual when working on a difficult issue I turned to my mentor Johan Greyling to discuss my options and explain what options I already explored. We sat down and took a long hard look at every aspect and part of the bolt. After deliberation and discussions and assistance from Johan Greyling I took the following route:

We decided the best option to get a sound base is to remove the flag safety and substitute it with the ghost ring base. I then copied the flag safety , file down the base ( I removed too much from the base) , but will use this item as a prototype ....when completed I will turn another one sine I now have all the dimensions.

This duplicate safety fits real snug in the safety housing.This will serve as a base for mounting a ghost ring. The ghost ring will be adjustable in height and wind-age will be adjusted by the front sight/bead.

Keep in mind members, there is another slide safety on the right side of the action that locks up the bolt.

As mentioned before I can increase the width of the disk to dove tail a ghost ring fully adjustable..I now have a lot of options on this sound base...

Removing the flag safety:




Turning a duplicate safety, just shorter :



Filing the safety to fit :


New safety, the base for the ghost ring extremely stable , no movement when lock in place ...
New safety, the base for the ghost ring extremely stable , no movement when lock in place ..Notice the base filed onto the new safety and the flat base on the cocking sleeve :


Safety fit into the safety housing , the disk ensure a broad base to fit the ghost ring and is extremely stable since it is standing on a flat base and under spring tension.

Ghost ring base secured and fit snug into the housing with spring tension keeping it on a flat base, no lateral/side to side movement at all:




Next phase will follow, constructing the ghost ring aperture sight...

I will keep the original flag safety in a safe place . When receiving my extra Mannlicher Schoenauer bolt I will have an extra bolt sleeve ..
