Slowfuse, if you get some extra reading time sometime, click on "30" in my sigline for a thread I started years ago about Marlin 336. There is a wealth of knowledge there from owners and shooters way more knowledgeable about it than me (even though I've learned MUCH from there and other places since then). Pretty much everything you'd want to know about the rifle has been discussed there at one time or another.
Still, I'll be interested to see which of the rifles you're looking at in this thread gets the pick.
I was very interested in a .45-70 (Marlin Guide Gun) for a while, but finally decided against it. Too much gun for where I live (on the east coast, some in Florida, some in Maine) and what I want to hunt (hogs and deer). If I was in Alaska or Labrador, might be different. Plus the ammo is soo expensive. (It'd be different if I reloaded.)
But I'm starting to crave an intermediate between my .30-30 and my .22 LR rifles (my only two). One of
the Ruger American Ranch rifles in .223 has my eye. I'm a fan of short barrels. May even chop my 336 down to 16.5" someday.
I know you're more interested in an AR platform, which is fine. I'm just saying I share your curiosity about .223/5.56. Never owned one before, so I'm studying them now.
