Shortest minimal OAL for a single shot rifle?

[3RDGEARGRNDRR]

Does anyone have the appropriate regulation for minimal length single shot rifle?
Is it the same as any other rifle? is it the same for Rimfire vs centerfire?
Many years ago, I thought I had read it had to be 26" or greater. Now I cannot find it. Wanted to be sure. Thanks in advance.

The 30" minimum OAL for semi-auto centerfire rifles is part of the assault weapons laws. [PC 12276.1(a)(3)]

The 26" minimum OAL for all rifles (centerfire & rimfire) is part of the short barrel rifle laws. [PC 12020(c)(2)]
