you can not put adjustable comb on synt.stock? i know that's all you asked for but by the time you buy a wood set ( around $200) , add adj comb($175) and then your old rib heighth will not match the comb on a trap stock and then, do you have the right barrel length? i am sure i forgot something?? hey buy a 390 trap 30" ready to go for around $650 - you will be way ahead!!! sorry- i am a taurus and cant help it!!!!!
