Don't see an hbar stamp in the barrel. This thing barely looks like the bolt has cycled.
Why is the flash hider upside down?
Watch this auction .

That auction has a a Colt 4x scope. They can go fo $300-$600 dollars by themselves.
The O.P. has a similar scope but if it's not a Colt Scope is adds little value.
Also, refer to post #2. Unless that's a birdcage FH, which it should not be, it's clearly on upside down.
