So, I am sold on the 6.5, especially in the AR platform. I just put together a 24" heavy-barrelled DPMS LR-260. I also have an 18" 5.56. Since ARs are like crack to me, I started to jones for a Grendel. Long story short, I got a Grendel-marked AA lower, LPK, mags, and ammo and then the Connecticut tragedy hit, along with its crazy prices. Where should I go about finding the rest, especially a barrel, bolt, and slick-sided upper? Thanks in advance.
