Does anyone know if it would be possible to switch out the stocks and fore-ends with the SX405's and 401's? In other words, take the synthetic black stock and foreend and switch it to the wood ones. The only measurement difference in the stocks is the comb and its only about 2/10 of an inch. Not sure about the fore-end but it's hard to imagine it being that different. It would be nice to be able to switch between a nice wood finish and a durable synthetic finish.
