Start with a top shelf receiver set. Seekins Precision is a great place to start. Glen's merchandise is the best in the business, and they build all thier parts in house.http://www.seekinsprecision.com/With that starting point, figure your budget and work your way into fire control, barrel, bolt carrier group, stock/ hand guard, etc. In that order.
