More stocks are coming as MFR's find out the Marlin 795/60/70PSS share the same stock...but its slow going.
Even with over 20 million total of those three rifles having been already sold...MFR's are lagging.
A Ruger stock can be modded, as can almost any stock, but be aware that it requires a LOT of attention to detail.
The 1022 is 1/2" wider than the 795, so you must figure out what to fill the stock with remove the gaps.
The trigger area has to be remolded to fit the 795.
Now these things are do-able, but VERY time intensive...takes dedication and it wouldn't hurt to have had a gunsmith course.
That being said, folks have fit 795's into MG-24 kits, P-90 airsoft shells, M-1 Garand stocks, and many others with great success.
You are only limited by your imagination and skill level.
