I was looking around for non-biased information about 6.5 Grendel round and realized some members on this board might have some experience. I was looking at building an AR with the 6.5 upper from Alexander Arms and prolly using an AR15 lower from Gunbroker or something. I was just wondering if anyone around here had used anything in 6.5 Grendel? Also if anyone has have you built yours with different uppers and lowers or just bought it fully assembled. I figured I could save a few hundred bucks if I go with a cheaper lower and just buy the upper from Alexander arms. anyways and Info about it would be appreciated.
