Curious if anyone can point out the differences between these 2 rifles? Savage's site isn't super helpful. The only differences I can tell (other than $300 price difference) is the TR has a 1" longer barrel (22" vs 21"), the TR has the much nicer Boyd's stock, a tactical bolt knob and a factory rail. I don't care about the stock as I'll be dropping it in a chassis, nor do I care about the rail as I'll put a DIP 20 MOA (or something similar). So for my intents and purposes, it seems the only differences are a 1" longer barrel and the tac bolt knob, did I miss anything? Also, how hard would it be to get a tac bolt knob put on? Just get the factory nob ground off and threaded, same as for a Rem 700? Or could a KRG bolt lift be made to fit? Looking at putting together a "tactical" trainer. Thanks for your help!
