I would really like to keep just iron sights on this gun, I have others with scopes for longer shots if needed. I have been on midwayUSA and they have more components for the 10/22 than I can afford. I was curious as to which ones would actually help the accuracy of the gun and which ones were just for show. A trigger is on my list, also I wouldn't mind getting upgraded sights at some point.
Mine shoots very well set up like this...
If you want to keep iron sights go with a set of tech sights.
Ruger® 10/22 Rifle - adjustable aperture sights
Also, sign up for an Appleseed shoot. That will do more for your accuracy than any gear.
