My main reason for offering up my suggestions was not knowing the knowledge level/skill of the OP. Semi-auto firearms require a bit more care and feeding than lever/pump/revolvers to keep running smoothly, not to mention the immediate actions needed to clear jams/misfires/FTF. Otherwise, I don’t disagree with your advice.
I think lever action rifles are the most under rated rifles today. The price for used lever actions has skyrocketed though. I recently bought an old Marlin 45-70 lever action and it is really mind blowing. At 20 yards it doesn’t put a hole through a watermelon - it vaporizes it. Ammo is pricy tho.
Doesn’t hurt to have a couple of quarts of good lube handy, either, to minimize malfunctions. And a couple of quarts of synthetic motor oil, on top of that.
