Aside from a chassis stock on the Precision and the plastic stock on the Predator and the long plastic tube hanging off the back of the bolt on the Precision rifle. What are, if any differences in the two? To me, the actions are the same and so are the bolts. Barrels on the Precision are a bit larger in diameter too. I got a guy slamming me on a Ruger forum telling me that I'm totally wrong. I had both and sold the RPR because I didnt see that much difference aside from the stocks. Been wrong before, I'm sure I can be wrong again.
