When the Remington Ti rifles first came out I bought one in 260 Rem just before I got transferred out of the country. When I came back they had been discontinued and the prices had shot up so much that I sold it.

As proof of Natman's law regarding gun parts (If you can't find a gun part you know you have, sell the gun. The part for the now departed gun will soon turn up), I've found a new firing pin and bolt shroud assembly. I remember that the original gun had Remington's ISS lock on the bolt shroud and that's why I bought a replacement without ISS.

My question:

Will this bolt shroud / firing pin assembly that was intended for a gun with ISS fit any short action 700 or only ones that originally came with ISS?

It's time to sell it and I want to make sure I describe the guns it will fit accurately.
