If it’s a Walnut oil finished stock, new ones in particular can be quite dry. I’ve had that with BSAs, FX, Webley etc. You’ll see people swear by different things, but for me the CCL gunstock conditioning oil is excellent for properly sealing the wood from the elements and enhancing it, whilst maintaining an understated matte finish. Obviously oils (of any type) are no good for varnished finishes. Takes a tiny bit of effort for a few days, but follow the instructions and you can’t go wrong.
