Torq spec on walther parrus?

Hey dudes I received my new walther parrus after I had to return the last one for an offset muzzle brake. Anyway umarex were awsome and sent me a new airgun and best part I get to keep the old stock from the last one! Now I have to can beat one up and keep one perfect. Anyway does anyone know the torq specs on the stock screws. I tightened the forearm screws and my usual German specifications which are goodentight. Well I heard a small crack in the wood when I did that. Not a huge deal just a small amount of splintering but nex time when I lock tight it I would like to do it to a good even torq. Does anyone have the inch lbs or Nm for them? Thanks dudes. BTW if you can ever get a parrus or terrus for 139 or 149 I'd jump on it. Beautiful stock, great fiber optic sights that work with a donny ronin screwed in. Basically a perfect gun for the doe. However at full price the plastic trigger and trigger guard would bar me from purchasing. I'd go with a krale special hw. Thanks dudes! 
 
Not sure on the torque requirements but at $139 to $148 I'd say it's the best bang for the buck for quality German springers for today's market price and even better when AoA was selling them for $99 a while back and I don't mind the plastic trigger which may even be a ballistic polymer. Congrats! YO!
 
Well, Raden, I'll actually answer your question!!! I use 22 inch-pounds on the forestock screws, and 30 on the trigger guard screw for my Walthers. I use those specs for all my rifles since it seems like most folks use them on theirs with no problems, and I've had no problems with mine. I use Vibra-tite on the threads, and a FAT Wrench to torque with. Nice rifle you bought. I have a Terrus, very nice to shoot and highly accurate.
