Hey all, looks like there is a lot of good info here! I don't have an AR yet, but hopefully within the next couple months I will. I'm really interested in the Spikes Tactical ST Vanguard when it comes out though. I just bought my first pistol two weekends ago, a Springfield TRP. Planning on heading down to Bluecore Sunday to fire it for the first time! I'm pretty stoked to see there is an indoor rifle range that isn't too far from where I live.
