Does the 10-556 come with locking washers?

A quick learner from Tennessee says:
Does this knob assembly come with locking washers to hold the two pieces in place?

As far as I'm aware, you should not need locking washers to hold the Swisco 10-556 Knob Assembly in place. However, I will look further into this situation and see if I can find more information regarding locking washers.

What holds the two pieces together?

Mike from SWISCO responded:
The female end of this knob set has a round spring clip that is "staked" into the center of the casting. This is done as a secondary manufacturing process. There is a hole in this spring clip that locks onto the male stem. Unfortunately, once the staking points are broken you cannot replace the spring clip. At this point, the knob would have to be replaced.
A quick learner from Trimble, TN says:
I assume that the knob assembly will be shipped in two separate pieces.
