Thoughts? They both are short actions, both use the same barrel size (.300AAC has 5R and a different twist). I have a Rem 700 SPS Tac in .308 Win in 20" and a .300AAC-SD (threaded) 16.5" and I have rolled the idea around to convert the Blackout to .308 Win to have a shorter barrel rifle that's threaded. To me... It appears that it would need the obvious rechambering AND a new bolt to handle the .308 face and a different internal magazine box for the longer round. Besides the three things listed above; what else is stopping this from being done? Yes I like compact rifles. Google turns up NOTHING on this. I mean one could just get a different barrel but I'm thinking rechambering is cheaper than having a new barrel put on it.
