I've got 2 stocks for mine, the shortened one always sat close on one side and I opened up that side mabey a mm with a sanding drum and a die grinder.
The other one is more central but very close considering how flexible it is....have considered opening that one up too but its not a problem untill its a problem.
I have stiffened a 595 tika forend with Nathan Forsters compound.....while it did work to an extent I think in the future I would just go for more barrel channel clearance and a bit of carbon fiber in the channel.
