As far as I know, the other synthetic option is from Ramline, if they are still making them. I haven't tried either, but I have heard more than one user say the comb on the ATI is higher than the Ramline's, so better for most scope mounts. You should check whether that is so for you. I doubt there are any new wooden stocks being manuractured for them now, but you might find some used if you can be patient and keep searching the EE on this website and other places where individuals are likely to advertise. I found a (wood) full pistol grip monte carlo buttstock in good serviceable condition for my No4Mk2 that way. Of course, if it is worth it to you, you could get a custom stock maker to produce whatever you want from a blank.
