Good Day

I am turning my shotgun into a pig gun, I still want to use it for ducks and geese so I want to be able to remove the pigsights when wingshooting and attach it when pig hunting.

These sights attach to the vented rib without machining and are fully adjustable, they are readily available in the US, however personally importing them is difficult.

Does anybody know where I can find such a product in SA

Thanks
