Got to thinking I haven't seen a 2007 USII red, white, blue Broad Stripe stock with blued hardware before, only stainless. The 2006 USST models with the standard alternating red, white, blue stock had the blued rec/barrel. I went to check the prefix of your serial to see if it was USST or USII thinking maybe stocks where swapped, but the prefix is cut off from the picture. However I did notice your serial as a hyphen in it, which is curious as the USST and USII models do not use a hyphen in their serial number. It also looks to have a poly trigger group.
I am curious to know more about your rifle. Does the box have a label you want to share?
