It's almost a given that if you buy an AR, you will need to reload unless you have lot of spendable cash,,,,so go for the reloading outfit first, so you can get your learning curve up.
As a beginner, find a couple of good reloading manuals first (before buying a lot of equipment), I would personally suggest the Lee 2nd Edition since it goes into detail about the 'whys'' as well as the 'hows' and you will have a good knowledge foundation...
Another would be from any of the major bullet/ammunition manufacturers....Hornady, Speer, Sierra, etc...but try to get the most current one available as they continually update the critical information.
For a beginning reloading kit, I'm not sure I would spend a bunch and Lee puts out a good basic set up for the least amount of money...Then RCBS, Hornady, Lyman, etc, (not necessarily in that order for expense)..You might consider checking some pawn shops if there are any local...I've found some good deals on specific items for my loading bench there..
You are looking at a press, scale, powder dippers or dispenser, hand primer (safer than the tube feed), dies and shell holder, case lube pad, case neck chamfer and deburring tool, and a mid priced caliper (electronic or dial)...There is a lot more items than can be had to go along with your reloading process, but that list will get you started..
Once you get started, a solid routine and attention to detail will keep you safer than anything else... distractions can be dangerous..Also, a notebook to keep track of what you do as to loads and measurements...Your records will be important as you go along..
