I am the son of Mr. And Mrs. Evilwrench, and I have joined mainly trying to have many questions answered. Im 17 and turning 18 in november, soooo I might be getting a gun or so for my birthday, and my dad and I have been talking about making me a 6.5 Grendel AR-10 style gun, and I was wondering who had a good barrel for a decent price, that would be compatible with a free float rail system because I am going to mount a Bipod on it with some other goodies, but mainly I need a recomendation for a reasonably priced 6.5 Grendel barrel. Thank you
