Fixing the Draws on a No4?

[Rwsgunsmithing]

As we can see by the document title, those are CMP rules, not NRA (which are different in many respects).

Rule 4.2.5 includes language that would seem to cover patched draws -

Shims made of wood, fabric, paper, metal or other similar material, of
types that were originally installed by military arsenals in these rifles and
that are placed between the stock and the action, barrel or trigger
assembly are permitted.

In practice, it's highly unusual that CMP games competitors are asked to remove a forestock for inspection - unless they have placed very high in national-level competition (or somebody snitches).

My apologizes, I meant to say CMP rules, not NRA.
