If I were building an accuracy, bench-hugging gun like that on the Mini-14 action, I would have the rear sight assembly milled off if an older model Mini, then have an extended 20 MOA 1913 base drilled, tapped, and red loc-tited onto the receiver. I might also look at tweaking the camming slot in the op-rod to extend the lock time, as well as float the barrel. Receiver would need to have the face trued, and the barrel would need to have the receiver shoulder trued as well, starting with a match-grade blank.
Another thing to consider is the dwell time difference on the Mini if you want a 24" barrel. I would consider an extended gas system length, as well as a lengthened stock, but a bull 20" barrel might be better to go with than a 24" anyway. The one in the picture has a custom gas block, most likely with a tuned gas plug inside with an optimum port diameter for that cartridge/dwell time combo.
Trigger would need work too of course, and the action either pillar or glass bedded.
