Wrong font on "A" (could be a dent), (can't see "S" clearly), wrong font on "5", "0" should be almost round, and Ord Esc is very obviously problematic. Don't have enough info to verify SLC, but it appears to me that someone has a roll stamping machine and the nerve to fake an 05 barrel. You can see the file mark at the rear of the front sight rib.

Every 05 barrel I have seen has a very smooth finish over the entire length of the barrel, and this one is just too rough.

It is a fake. Good eye, John.

Squashed barrel for over $300? Rare? BS! Most I have paid for an 05 BBL was $150 and it looked like it was new inside and out.
