For a cheap semi auto what do you expect? This is not a Remington 700 heavy barrel. As .5MOA pointed out above the rifle was never designed to be a DMR or precision rifle. It's called a ranch rifle for a reason. It was designed to be reliable, be able to shoot a coyote at 200 yards and shoot cans off a fence post or in a gravel pit at 25-50 yards.
I personally want more out of my rifles and can afford to spend $3000+ on a 223 semi auto so I sold my mini-14 but for someone that just wants a fun non restricted on a budget it's fine. If you stick to Ruger brand magazines and try a few different types of ammo to find it's favorite food you have a rifle that is capable of doing what it was designed to do.
If you think every rifle over $500 should shoot 1 moa or better then you are delusional and need to reassess your expectations and throw in a good dose of reality.
If you want an accurate 223 you need to look at the HK SL8 series, I've owned 3 of them in various configurations and they are definitely the most accurate out of the box factory rifle available but you're looking at $2000+ then the money starts adding up if you want to modify it.
I understand your pont, I own a target and a ranch.. But I want the poster to explain how 2.5 MOA is inaccurate.
