I am thinking about building my own AR-15 lower half, then buying a complete upper to put on it. It will be my first time putting one together, and I've read that a lot of problems with reliability come from home built AR's. If I'm only building the lower though, and using high quality parts, how much risk is there of me ending up with an unreliable rifle?
