Looking for an aperture sight

[carbonfibrebob]

I'm new to the forum. I am looking for an aperture sight for a new to me 99 in 358 Win. It is the newer style with the tang safety. The mounting holes on top of the receiver are 1/2" center to center. Any leads would be most appreciated.

I think you are looking for a Williams Gun Sight FP-99S

It attaches to the receiver and not the tang.
I checked a few places and it's out of stock.

Looks like that sight has been discontinued. Check Ebay or the gun auction sights for a used one, they turn up.
