I'm beginning to research my next AR-15. I want to get a varminter but I have some questions. The one I'm looking at is Stag Arms. It has a 24'' steel barrel with a 1in8'' twist. Fluted/free floating aluminum handguard, a 2-stage match trigger and an A2 stock. Are these some good features? What's the benefit of the free floating handguard? How much distance will this go over my regular 16'' barrel M4? I have more questions but will post them later.
