Project Appleseed

Hi!
I am in need of some assistance with a 10/22. (hopefully, the picture will attach)
On the action spring rod, doing business as the "Cocking Handle, Guide Rod & Recoil Spring Assembly", there is a small steel(?) bead around the rod, between the spring and cocking handle... hopefully as seen in red in the pic/attached.
If anyone sees one come flying by them, it's probably mine. Could you grab it for me? 
Mine launched while I was trying to put the bolt back in. 
I actually heard it clink off the glass face of the clock on the shelf. From there...? (need a shoulder shrug emoji)

Alternately, does anyone know if it is needed? Or where I can source one if it is? 

Thanks, y'all are great,
Burnett

p.s. yeah, I'm kind of having fun with the emojis. You know the saying, simple pleasures...

 I believe that is considered a factory assembly and is crimped. I do not know of anyone selling anything other than springs and the whole assembly. But, the assembly is 6 bucks for the Ruger one at midway. There are also aftermarket ones for more money.

The bead is not needed.  I run several 10/22 without beads and all work just fine.

I have two 10/22's and somehow never noticed that bead before. Looking around at the aftermarket options, I see the Volquartsen charging handle assemblies have a bead but the Pike Arms and the Tandemkross ones do not. I would be inclined to use it without the bead and see what happens.

Loking on the drawing, the purpose of the bead is to center the spring around the rod. Practically, rod and spring are so long, so spring moves around a lot anyway, and it makes a little sense to fix the very end of the spring.

Little sense, unless Ruger has several occasions of the spring walking off the rod over the course of many rounds shot - it's a pure speculation of mine, I'm not a gunsmith. And you have to have a cut spring  for that to happen - where the end-twists are not pushed together, but rather an open end is left.

I would let it go after visual inspection and functional test.

The Kidd setup also lacks the bead and the crimp - works fine.

The bead makes assembly of the bolt and spring easier,  no launching of spring if it slips. Guess it also gives a few pounds pressure on the bolt.

The cocking handle is crimped on, but someone years ago clued me into the cocking handles of the OEM 10/22 .22 Magnum. They were à little bit larger and I liked them. The spring rod on them was longer so you had to swap the handles to the .22LR rod, which required sanding/filing just enough of the crimp off.  Well, reassembly got away from me this time.
Attached should be a pic of the two versions.

edit: It's there. It's upside down for some reason, but it's there.
The standard .22LR version is on the top and the magnum version is on the bottom in the pic.

As others have said, you don't need the bead.
I like Kidd charging rod/spring/handle parts. They don't come as an assembly, the handle and spring are not captured by a crimp on the rod. You just have to pay a little more attention when assembling or disassembling.
The Kidd rod is polished, and it's operation is smoooooth. While you have yours out, sand and polish all the ridges off of your guide rod, it'll make a difference in smoother cycling.
