Well the upper made it here today in perfect condition. I mounted it to the DPMS lower I had and it fit tight with no slop. I can now see I will need a new barrel nut, delta ring, spring washer, front cap, and snap ring to swap in the MOE handguard.
I did buy a box of Hornady ammo and plan on putting some rounds thru it tomorrow. Here in Indy at a local gun shop ammo was $33/box. Is that about what .450 ammo sells for everywhere?
I think I'm going to like this thing!
