After a lot of research and looking around I finally settled on a CORE Systems AR. The model I purchased was the CORE 15 keymod scout. And its fit and finish are awesome, won't make it out to the range till Monday, but am chomping at the bit to see what it can do with all the reviews I have read. Already bought 4 pmags and enough ammo to fill them. Bipod and scope to use temporarily. Any suggestion?
