Actions with long barrel threads

[JARHEAD1371]

I'm researching different actions for my next build and I'm narrowing the list by barrel tennon length. I know of a few that are over 1" in length (M2013, Raptor, and Surgeon XL). I'm wondering if I'm missing any.
The reason for the length requirement is I believe the longer the tennon, the stronger and stiffer the barreled action will be, especially with a supressor hanging on the muzzle.
Right now, the M2013 (1.37" and a heavy duty action) is my first choice and the Surgeon XL is off the list due to the lack of supply.

Thanks in advance for any input or advise.
