Swapping Complet toggle assembly

[DonVoigt]

Chances of a problem are slim.

There is no difference in a long receiver and short receiver from the breech face back.
The extra "length" is all at the front and they do require a different length shank on the barrel; so the toggles are identical(within tolerance).

Here is a long shank barrel(made for the long receiver) installed in a "short" receiver using a spacer ring. The difference in the receivers is approx 1/10", i.e. the thickness of the ring shown.
