A BB and retractable pen spring cut to size would do. (Smirk!)
Speaking of using what I have on hand. Anyone who owns a Fortitude knows that the cheek rest is really low for a gun that requires a scope.
Here is my cheap fix. Duct tape and pipe insulation tubing. As the LOP is VERY short I also added a store bought butt pad to lengthen that a little over an inch, I think, but I wish it were a bit more for me. Not to mention that the original butt material was slippery and made it VERY hard to hold the gun steady to my shoulder, especially with the original low cheek weld. The slip on butt pad fixed the slipping and almost fixed the LOP. The cheek rest fix is perfect, if not pretty.

Not pretty, but it works well and has since I first owned the AG. (grin)
p.s.
Also did the duct tape fix for the barrel band shroud support. That one should not be necessary... but it is if I want consistent accurate/precise groups with the Fortitude.

Just make sure the BB is no more than .173 and the spring is no more than 1/2 inch, + or - a micron or 2... or it will be ARMAGEDDON! Especially if you forget the LUBERCATION!
Lubercation... LOL!

I would agree. On the Prod/Fortitude breech, there is not much room from the top of the dovetail to the bolt barrel. Getting a short spring, ball, and set-screw in there might be a challenge. It is a good solution though, and crosman used it on the Mrod.
FWIW: The Fortitude breech is very similiar to Prod. It is slightly taller to fit the larger diameter Mrod shroud, front breech screws in different location, and no machining to allow for left side bolt install. I think the bolt lug is slightly longer, but would have to check notes.
This problem can exist on the 1701, 1720, Prod and Fortitude breeches. It is a matter of machined tolerances. Most of the time, some moly grease on the main bolt barrel will add enough drag that the bolt won't fall back when you turn it upside down. You might try that when you replace the insulation. It will take more clean-up to adheare the tape, though.
The O-ring on the back of the bolt works well too.
Best way I have found to fix this is to drill and tap a hole in the top of the breech. Put a small piece of an o-ring in the hole and then a set screw. Screw the set screw down until the bolt behaves as you would like it to.
I would just drill that hole a little bigger not all the way through and tap it and run a ball bearing and spring chased with a grubscrew to adjust tension and drill a dimple in the correct timed bolt closed home and handle down position.
I would think the o-ring may get eaten-pulled out by the bolt after it wears and bind the bolt probe after it falls completely through.
