I find basic clone actions interesting. If we don’t count ordinary pins, springs, or the trigger that will be an aftermarket item on 99% of builds, there are only 9 or ten rather simple parts. The original dimensions and clearances have been long accepted as quite good as is - so other than a few cosmetic changes, you’re not buying anything new. The materials in a factory Remington are nothing special, and unless a clone is bragging about their steel selection, it’s probably rather ordinary chrome moly heat treated to similar hardnesses. Everything is made on CNC machines, so unless a machine is clapped out, accuracy in dimensions is pretty much the same. The amount of cock on close will be very similar. Regular old Remington receivers without any work will shoot well under MOA, so for hunting actions that don’t brag about their dimensional accuracy and trueness, I doubt it’s better than the original. My 60 year old Remington is so close to current production 700’s, a new bolt fits my old receiver within a few thousandths all over. Ordinary clones have zero incentive to change anything - I would bet lunch a 307 bolt will fit my old gun.
There’s a much larger difference between toasters, or Ford vs Chevy pickups.
