How is the accuracy of your Ruger Mini14? I've heard stories about them having problems. Some are tackdrivers out of the box and others may as well shoot sideways.
When I bought mine in '81 or so it wasn't totally awful, 3-4 inch 5rd groups off a bench at 100 yards with good ammo, but not great either. I've tweaked it some and with the synthetic stock I can keep it pretty much under 2 inches now and as good as 1 1/4 in. with match or handloaded ammo and a scope on my best day. I've read a test report by Massad Ayoob that the recent manufactured Mini14's are shooting 2inch groups out of the box now.
Also, how well do your 30rd mags feed? Any problems?
I've had good luck with mine although with several moves and some time in a storage locker I had some rust spots on a couple. Again, I bought them in the early '80s and can't recall from who. I did have one I picked up cheap at a gun show back then that wouldn't feed every 4th or 5th shot so I tossed it. The only other problems I've had with my Mini was caused by some really cheap surplus ammo I had picked up from a guy that must have stored it in his wood shed. That's long gone now but it worked well enough for making bean cans dance.
Do you have someone watching your back?
At least 1 and if things go as planned/prepared 4 or 5 shooters riding herd on the womenfolk and kids. (Before anyone starts screaming SEXIST!, 2 of the shooters are women and they are so good if things look really dangerous, I want them walking point.)
