you could also buy a cheap donor action with a mag bolt face and get a pre-fit from anyone who does them, which is now quite a few reputable sources. Would probably be about the same cost but you'd have a better barrel. also assuming you're going to replace the stock on both the CTR and a lite. a 300WM can be had for $550 +$450 barrel plus $400 KRG Bravo $1400
versus $900+ for CTR, +200 gunsmithing, $200 $450 bolt??, plus bravo on top with new AI mags anyways $1700 give or take
