I'm looking to build an AR. Anyonee have an idea about decent combinations to get me started?
Start by reading everything you can on all of the various AR15 forums. That way you can educate yourself and be able to make wise decisions when purchasing your parts.
Any more, asking for help on a forum will just confuse you, because every Tom, Dick, and Harry that has ever slapped a bunch of parts together will tell you 1000 different things.
Take your time, read, learn, then ask questions.
