This gun was stocked with the cast off, even the top tang is directed to the right. I suspect it will need restocked to remedy
Dicksons are notoriously difficult to bend, most of the time impossible. The fillets on the stock are very fragile and bending can do damage to them. Most gunmakers wont even attempt to bend a Dickson RA. I said most....theres some out there that have done it with some success, but usually the successful bends are pretty minute. Youre not going to move that stock 1/4 cast off to 1/4 cast on. You might be able to get to neutral before damage occurs. Its not uncommon to bend action tangs when bending stocks too. On big bends, it has to be done or youll have the tangs springing from the wood.
That is one of the big bugaboos with buying a Dickson RA. It has to fit pretty well when you buy it because adjustments are pretty limited, restocking is usually required to make it work well for the new owner. And as you might already know....restocking a Dickson RA is not cheap.
