I've been shooting the heck out of the same Ruger 1022 for 30 years. Last year I finally took it apart and gave it a detailed cleaning. Its probably the #1 selling 22 rifle in the US. I can keep the groups within less than 1" at 50 yards all day long. They are optics friendly and come with iron sights as well, and are available in stainless. Semi automatic, so even though its "only" a 22, there is a capability for rapid firepower, if needed. Detachable mags that are available in capacities from 10 rounds to who knows what, so there is your quick reload capability- if needed. Also, several mags no matter the capacity gives backup in the event that one or more is lost or becomes inoperable. Mine has a 1-4 scope with illuminated reticle- capability for low light, along with the power range to use it as a RDS or dialed to max power for sufficient magnification within the range of a 22 LR. Choate and Butler Creek both make 1022 collapsible stocks that fold to the side for storage- I can't vouch for the quality of either, but I did have a similar Choate side folder on a mini 14 in the 80's that was satisfactory in quality and durability. It seems to me, that a stainless 1022 with one of these collapsible stocks, several spare mags, and a scope like the one on mine, a simple sling, a supply of ammo, a small cleaning kit in a soap dish, and an extra battery or 2 for the illuminated scope, all packed into a soft case would be the ideal 22 survival rifle for any situation, with the primary limitation being that its a 22.
