Nubo,
Advantage Timber or Mossy Oak "Obsession"? MO is a 2004. You should be able to find a small logo or 2 somewhere on the pattern.
Also look for the sealed bearings on the cams, bearings = 2004.
Oh yeah......does it have the "Limb Squid" style Vibrablocks? They have soft arms sticking out in a radial pattern that from above looks like a roadkilled squid
.......that's also another indicator of a 2004.
And I think we'll let ya slide on shooting it at 20-40 below zero.[:-]
