Have a rifle from the mid 2000s, a 243 converting to 35 remington for the wife and kid.. would like an adjustable or shorter stock so looking at the newer stocks offered on the newer rifles from the last few years.. any issue fitting the older actions to the newer stocks or is it a drop in? This particular rifle has a detachable box mag

Edit: I noticed the newer stocks I'm seeing are bottom bolt release (mine is TOP). Will these also work if I just dremel out a slot for.tje bolt release? Would like to stick with a factory savage stock for the adjustable LOP
