FWIW, I acquired an old 180 series Mini 14 in the early '90's, supposedly the worst of the worst, as far as accuracy goes. (I didn't know that back then, go figger! :lol: ) Owner said it didn't shoot worth a darn, and it didn't! Turns out all he shot out of it was the cheap Norinco crap available back then, and wasn't much on cleaning it.... :roll: After about 3 days of off and on scrubbing and soaking, a little light stone work, she'll do 1-1/2 MOA if the shooter's up for it.
I actually shot a couple of high power rifle matches with it, and stayed fairly competitive, all things considering. Until the 600 yd line at the last 1, where the durn shooter couldn't seem to get his sights up on target. :? A spotting scope would have helped, definitely not in the budget, tho. Plus, I had never shot it at that distance before, and was guessing. Kinda funny how the guys with the fancy a$$ ARs wouldn't say anything to the young guy there by himself back then....
I just picked up a 582 series Mini in .223, and have been playing with 1 in 6.8 for a little bit. Lack of ammo and components, as well as time has been a factor, but I've been squirreling some 6.8 shtuff away. Hopefully this summer when work's slow again I can get a handle on how good the 6.8 and the new .223 will do. I got the new .223 because the old eyes aren't quite what they used to be, and mounting a scope on the 180 isn't a great option. Besides, my son's got his eye on my old 180! :lol:
Not into the AR platform, played with it years back, didn't care for it. I like the Minis. There's a lot of good advice on here. Stick it out and you'll have a sweet handling and shooting rifle in short order!
