I highly recommend the Henry U.S. Survival Rifle. I also call it the "AR-7" but that designation really belongs to Charter Arms who made an inferior product.
I have put thousands of rounds through my Henry AR-7 with few, if any problems. The firearm is easy to maintain and clean. It is remarkably accurate. It takes a lot of hard use. Everybody on the range agrees: it's a FUN rifle to shoot. The people who really like it, do so because it is so light weight.
There are some nuances you need to be aware of. After about 32 rounds, the barrel warms up and the barrel screw loosens. This problem is especially noticeable on indoor ranges during the winter time when your AR-7 gets cold from being stored in your trunk. You'll know when it happens! Suddenly, you won't be able to hit the broad side of a barn. Check the barrel screw and don't be surprised if its loose.
There is a plate on the receiver housing that is held in by a screw. It tends to come loose under the same kind of winter conditions. If your Henry starts mis-feeding, check it. Have a small screwdriver or gun tool handy and tighten it up.
The rifle butt cap tends to come loose after hard useage. I've beefed up the seal with plumbers' tape. This works fine at room temperature. Unfortunately, if my AR-7 has been sitting in the sun for any length of time, even the plumbers' tape won't help.
If your AR-7 has been sitting in the sun (while packed in its stock) don't hold it with the butt cap down when it's packed. Use some duct tape to hold the butt cap on if it's going to be in the sun for a while. Or carry it in a small carrying case, backpack, toolbox or whatever. Perhaps someone will have a better tip for dealing with this.
All in all, the Henry AR-7 is a great firearm and lots of fun to use on the range. I'll take it over a Ruger 10/22 take-down any day because it's lighter, floats, takes punishment and cleans easily in the field. I can put a sling around my Ruger 10/22 and call it a day if I'm taking it into the field. For real portability and overall survivability, I'll take my Henry AR-7.
