Really enjoying this thread. It has all been said here about the comparison.
My 1 pristine safe queen mini-14 is never going to shoot like my AR's.. Ever. I came to grips with that a long time ago. Honestly, if I was getting 1.5-2'' groups in a 5 or 10 shot group out of my mini-14, I'd think I died and went to heaven.
I bought the mini off a TX State Trooper in '05, headed for the bayou just after Wilma hit NO and the LA coastline. At the time, I bought it for the M14 open-bolt cool factor, its pristine condition, and to bolster 5.56 friendly platforms.
I've never been sorry for a nickel I spent on my mini. It has functioned flawlessly. I still own it for the reasons I bought it, beauty, fun factor, and SHTF factor.
For $500, I've got a completely outfitted little 5.56 lead slinger that sits in its own bugout bag with multiple magazines and 300 rds of ammo.
But.. if I am finding society is breaking down, I can put a mini in a family member, neighbor, or friend's hand.
I love my mini for what it is.
