PJR, as one who has owned both the older model Mini-14, and now a brand new Mini, I will attest to the fact that the new versions are way, way more accurate than the old. My new one is a standard Ranch Rifle, stainless with synthetic stock and 18.5 inch barrel. I will even say that I think the standard two stage trigger is pretty good.
So far I've only put 100 rounds through it using the standard iron sights at about 75-100 feet. We were plinking....shooting at water or milk bottles (not jugs), and some steel discs. I never shoot with irons as my eyes are getting "old", but I was popping some of these targets and when I missed it was pretty close. I did not baby the rifle at all, going through 20 round full magazines, and maybe resting it for 5 minutes or so between mags. The barrel got hot, but as far as I could tell, it was not stringing shots. The irons needed no adjusting out of the box.
The receiver/breech area was amazingly clean after the session. Recoil is very comfortable; no muzzle brake is needed on this rifle. I like the 18.5 inch barrel because it gets more out of the .223/5.56 round, and the rifle seems to balance well and hold steady.
There wasn't a single malfunction of any kind during these first 100 rounds.
I haven't mounted glass on it yet, but this time I'm going with a Burris TRS-25 red dot just for fun. If I don't like that choice, I'll put either a 1-4x or 2-7x on it.
Don't take my word for any of this, though. Randy Wakeman is a well known, credible gun reviewer/hunter who publishes on his own site and also on Chuck Hawk's site. These guys don't accept advertising from gun makers, so they call them the way they see them.
The link below, on Randy's free site, is Randy's follow up session with the new Mini-14 in which he has mounted a scope on it and shoots at a paper target for the record. It's a short video and you'll see the target. There's a link within this story to his original, lengthy review of the rifle. He flatly states that it is a minute of angle rifle, box stock. He's undoubtedly a way better shooter than I'll ever be, but I've found his reviews to be spot on. I've even bought a couple of firearms based on his reviews.

You won't be disappointed with the new Mini-14.
