I think for that price it's not a bad gun. It's very simple. The following comments are made assuming that picture is accurate. One thing to be aware of is that you're going to be spending money on some sort of sight. You'll either need an optic or a pair of iron sights and you can expect to spend a $100 easily on a set of those. The other potential downside is that there is no forward assist. It's arguable that you won't need it, especially on a range gun but it's something to consider. The biggest downside is that it's one of the parts that is difficult to just swap out on a whim.

The 1/9 twist will be good for you. It plays nice with 55gr ammo which is good for cheaper plinking. The cool thing about the AR platform is that it's really easy to piece things together depending on what you want to change and as the money comes in to really customize it. As long as you put in a little care the rifle should treat you well.

That's my two cents on the thread.
