i put a k 32 recevoir and forend iron i purchased on auction, added a k 80 fancy fajen ??? trap wood set with adj. comb and adj. recoil pad and put a san remo top single bbl. 32 in. factory imp./ mod. choked.the trigger guard is k 80 engraved. some parts i got in trade , some i purchased at good price. this set up makes a nice shooting and nice looking trap gun. the recevoir is standard o/u recevoir so if i find a o/u bbl i could use it to try dubbles when i can hit the singles. i am just starting to shoot trap. so i am as green as grass. the recevoir has just come back from krieghoff where it was gone through and came back like new. how can you put a valve on this parts gun, im thinking the value of seperate parts totaled together would come close to value.
