I sold my first and only Mini, wished I had it back.
It was reliable as the day is long, accuracy about 4" @ 100 yds offhand with hand loads or factory loads.
Muzzle flash was spectacular along with the noise, it always turned heads at the range with the first magazine full.
I bought mine at the height of the Brady Ban, and high cap mag's were at a premium, now days not so much.
It takes MINI'mum amount of care, to keep a Mini shooting, throw it behind the seat of your pickup, and forget about it, it will shoot when you decide you need it.
Buy a stainless Ranch, if you like steel sights there are several aftermarket to choose from, I couldn't shoot any better groups with a 4X scope with the factory but someone else may be able to do so.
Don't let the AR guys influence your decision, shoot one and you'll see what is addictive about them.
