How does it compare to its X-bolt cousin?
About the same....except it is a U.S. produced rifle.
Accuracy... the Model 70 was never a tack driver, there have been the exception every now and again, but for the most part, the Model 70 is a 2"@100y, sometimes a bit less, rifle. Compares with the X-Bolt.
Smoothness of operation... compared to what exactly, the Model 70 is smooth enough, certainly it is not a custom polished, squared receiver, PVD coated bolt ways, rifle in reference to 'smoothness', but it is certainly smooth enough! The FN Model 70 is the best engineered Model 70 we have seen since the 60's, manufacturing costs taken into consideration!
Recoil pad... there are 'better' and more effective ones out there, even on some of the other brand rifles, but it is what it is on the Model 70, and it is a pretty good pad.
The MOA trigger, well, I personally would give you a bucket of cold spit for all of the MOA triggers made, but comparative to say to Remington's latest abortion, it is not bad! I think, unless you have had the opportunity to have used and or have manufactured some of the 'better' triggers of late, you'll not know what you have missed in the past, and you'll probably not criticize the MOA much...honestly, for a safe, production trigger, it'll do! At least it doesn't feel like a bunch of cheap erector set parts held together with wood screws.... take note, never mind-
The Model 70 is a pretty good and well built rifle, it will preform solidly, and with exception to the flimsy, easily damaged safety lever, the rifle will give you years of excellent service.
