the remmy is one of the few rifles in 22 left, that include fully adjustable rear site assy., and a front site. If you get 3rd generation mags for remmy , they have a 10 inside a circle, this takes care of 90 % of the fte ftf problems of the remmy. to take care of the other 10%, simply remove the action from the receiver, take out back piece that holds the guide rods. Remove the guide rods, and then finger tighten them in , back in, just enough to close the end piece back up on them. The big prob with the guide rods, is they are put in too tight at the factory, and they bind when the bolt assy travels rearward; loosening them all the way out as much as possible cures this problem.
Out of the box, with no mods, the remmy is way more accurate than a ruger.
