I just bought a Savage Model 99 and need a couple opinions. First, which model 99 do you think it is? I'm not sure how to post pics. The rifle has a straight grip and originally had a crescent butt stock. Plain...no checkering. Has the shell counter and a cocking indicator. Round barrel that is 26". It's a takedown model chambered in 303 savage. Serial # is 225,XXX. Front site is a "Jake" as described on Savage99.com. Second opinion has to do with the stock. Apparently, the crescent plate was removed, butt flattened, and butt recoil pad put on. Is it better to leave the original stock on with these modifications or should I replace with a new crescent stock? Thanks...
