ok wanting to get a ar but notsure what cal i want all i know for sure is it will be a yote gun more than anything else so gonna get a flattop upper. so since i cant make my mind up yet just gonna get a lower and go from there. So what lower to get is a rock river stag or other top names truly better than the cheaper ones or just the part kits they put in them. if the lower is just a lower that holds the parts you put in it it dont matter what the name on the side says. any input would be great.
thanks
