This may sound like heresy but...

I have/had 2 factory blueprinted actions. Still have a FTR, had and sold a Stealth Evolution. Between those two and the many other I have/had I honestly could not tell you the difference by looking at them or shooting them. The Stealth Evo was not a particularly smooth action. The FTR (stainless) action is smoother than average, but doesn't even come close to a stainless FVSS action I had and regrettably sold a couple years ago. The FTR is insanely accurate, but I would argue that has a lot more to do with the barrel and load development than the action. Even with a bolt lift kit, the lift is still heavier than I would like it.

A couple guys I shoot F-class with use the GRS stocks and really like them. They seem like really high quality and have great ergonomics. With the GRS being 5lbs lighter, I would much rather carry it around than the Precision.

Yes, walking around with a 15lb rifle sucks. Great from the bench, but after a mile or two it gets fatiguing.
