Large or Small Shank?

[centershot]

How can I tell if my factory 110 is large or small without taking the barrel off?

The barrel nut are different lengths between the large and small shank. Large is 5/8" long and small is 7/8" long.

Just as Swissfan posted. Here’s another pic of just the Barrel nuts. Other than the threading size, the two Actions are identical. Same OD, Length, Screw Spacing, etc.
