Hi Quick, I just got off the phone with Jennifer after ordering a set of synthetic stocks. I tried to order a standard rifle synthetic forearm for a 45/70 but she told me all synthetic rifle forearms were the same size barrel channels and it may or may not be a bit snug on a 45/70 barrel and might have to be sanded out, I know that is a bit of a pain but at least no refinishing is required as in doing a wooden stock. The synthetic forearm I used to have from a .22 Mag Sportster was just a bit snug on my heavy .280 barrel and I could push it on without sanding and I believe my .280 barrel and my 45/70 barrel are the same outside dimensions.
The question is do you know if there are differnet synthetic forearms for different barrel measuremants?...Thanks....<><....
