The Remington 700 ML/MLS typically come with a threaded cocking piece.
All other variants of the 700 and Model 7 almost certainly use an unthreaded cocking piece.
These called by many names: Firing pin end, cocking arm, firing pin guide, firing pin head... etc. Remington calls this same part a different name depending what rifle they use it on, or even changes the name in the same manual many times... so do not get hung up on names. Most every Remington 700, or Model 7 use the un-threaded version. The threaded version was only used on the 700 ML and 700 MLS. However I've run across a few 700 ML rifles that use the un-threaded cocking piece.
The threaded pieces we have for sale are taken out of used firing pin assemblies. Un-threaded are new, direct from Remington.
Threaded cocking pieces thread onto the end of the firing pin. The cross pin only is there to keep them from un screwing... so you can use a simple roll pin with them.
Un-threaded cocking pieces slide onto the firing pin and are only held on by the cross pin; the un-threaded cocking pieces must be held on with a solid 3/32 dowel pin

On Remington 700ML/MLS rifles, I've only seen people needing to replace a cocking piece if they are using the old, leaky, gets blow-back everywhere ignition systems.
Why not fix your rifle 'right' and get our sealed breech system that stops crud from binding up your bolt and breaking your cocking piece?
