i have had a couple Charter Arms AR-7's. I believe the primary difference is the alloy sleeved barrel rather than plastic sleeved barrel
When clean and lubed, they are both 100% reliable with high velocity ammo.
If you attempt to plink with them, they quickly get fouled and will start to have problems after a couple hundred rounds.
They are more than 'survival' accurate, for potting grouse, ptarmigan, rabbits, marmots etc.
I have no experience with the Henry made version, though I have no hesitation recommending a Charter Arms version, as long as you do not try to compare its performance to a 10/22 or a CZ 452.
