A lever action rifle would be the last thing I would get as a shtf weapon.
Weapon, in a shtf scenario that is what you want, a weapon.
If you want a good shtf weapon KEEP the AR, if its a cheap AR sell it. Use the money to buy a M&P Sport, M14, or Kel-Tec SU16. If you want a gun that is less accurate out to range but "more durable" get an AK or SKS.
Hell, save up for the next two months, buy a Henry and keep the AR.
