I was looking at a used AR15 at a gun shop yesterday. The lower was stamped Bushmaster. I looked at the upper and couldn't find any marking to verify it is a Bushmaster upper. At the muzzle end of the barrel it was stamped "B MP 5.56 Nato 1/9 H BAR" Back on the carry handle it has "FK" cast into it. Is there anyway to tell if this a Bushmaster upper? Thanks Tim

That is what Bushmaster puts on their barrels. Go to the Bushmaster website and read their FAQ section. I believe they cover that exact question there.
