Nothing wrong with being “biased”, I call them “preferences” ;^)
It’s on my “nice to have” list, I’ve been looking at the M1A1 as well...that’s one of the EBR’s (evil black rifles).
Looking for a hunting rifle that can “reach out and touch” both 4 legged critters and 2 legged varmints.
I also secretly like the AR-10...it's a lot cheaper than the M1A and chucks .308 just fine...but don't tell anyone. I'd lose friends. ;-)
