I'd be highly suspect of that Ruger being a 20" barrel, Ultralight.
The Model designation on the box has it as a "KM77RMKIIP".
Translates to a Ruger KM= Stainless M77 R=with rings, MKII=bolt action with 3 position saftey, P=Zytel (skeleton) stock.
If you look at picture #3 at the auction. It shows/has the Caliber designation, cal. 223, stamped on the barrel shank (22" barrel). The Ultralight barrels 20" had a short shank barrel, and there is not enough room for a cal. designation. UL cal. designation is stamped forward of the barrel shank.
He may have measured the barrel wrong, or the barrel has been cut.]
I concur with your assessment and unfortunately there is no L in the designation indicating the 20” “A” contour barrel. It’s a standard 22” rifle.
