Not exactly sure what you are asking  There are a whole bunch of things contributing to accuracy and the actual actual action (and "Stevens" covers a number of types and variations, so rather than apples to oranges you've got a whole fruit salad) barrels ammo, shooter skills, stock, bench  set-up, sights,  conditions, gunsmith assembly skills, and oh yeah the action.   Manufacturer and actual action probably are not the most significant.

That said with an optimum assembly of factors I've seen "Stevens"  22rfs shoot sub MOA@100 at Etna Green.  However I've also seen Ballards, Winchesters, Remingtons, BSA Martinis, Euro-Martinis, even Rugers that will do the same.   Its a hellova lot more than just the brand name

Curiousl how you sight through two aperatures at the same time? Maybe you need to add a scope also?
Just kidding! Nice rifle and great groups. Darn things are realy accurate when you consider that they are basicly an improved Favorite.

Actually, it is a slip fit barrel just like a Favorite--uses a slotted and threaded stud rather than a stud with a loop or knurled knob.  Also, this one is a # 4 countour barrel--1 being skinniest and 5 the heaviest according to my DeHaas book. One trick is make sure the threads are good and clean and use anti-sieze on them.  Had trouble once after a 10 yr. layup--took the barrel off, ran the screw all the way in to clean out the threads--didn't want to use a thread chaser and remove any metal.  Put the barrel back in and antisieze on the threads and screwed it back in good and tight--barrel has been tight now for 3 yrs.
Slumlord, believe it or not, I did use both rear sights for those groups.  It was a tiny sight picture, but you really knew when it was "on".  Lately for bench rest I've take to using the rear Lyman 144 and removing the disk on the front 44L reciever sight, and using the 44L as a "ghost ring". 
Someday I'll get around to playing with a circle aperture insert on the front sight, rather than a lollipop and a 6 O'clock hold.  That'll probably be next summer when it warms up!
Another thing I've played with is using the front sight for 50 yd. work and the rear sight for 100 yd zero's but overall I do like the 144 best for eye relief and the longer sight radius.
PS--my Dad was still using this to pop the occasional racoon after his pet geese 12 yrs ago with just the reciever sight with disk removed (as a ghost sight)
