The actions that state they are REM700 clones should fit a stock or chassis that is also REM700 pattern. Timber stocks will need glass-bedding to the action, but a synthetic or metal chassis would be fine.
A lot of the time it is the magazine that will cause feed issues, so look to get an action and stock/chasis combination that uses a standard AICS magazine (or other quality magazine) rather than an obscure magazine type.
If you haven't bought a gun/action yet, also consider a non-REM700 footprint too as MDT make chassis for all the common actions. Howa, Tikka, Savage, Sako (etc.) are all great platforms.
