I knew you were a notch or two up from me. I did my Beretta 20 bore, just slapped a bit of sapele on the end to get it right, and never have bothered to do it properly
Remove stock. And forend. Strip BOTH of any lacquer, varnish or finish. Use Rustin's wood stain as it is spirit based and won't raise grain. Using a stain that will darken the wood enough that both then match. Then refinish. In this case three coats per side of Rustoleum spray semi-matt varnish. B & Q or Homebase sell it. Left to dry between each coat. Here's one I did earlier, as they say, my AYA .410" that is now at auction. The extension piece was shaped and fitted by a stocker in the trade. But left unfinished from the raw wood. So all the colour and finish you see was done by me as described.
