I feel bad about paying 575 for mine 2 yrs ago. Mine has the adj sights, and appears to have been shot very little when i got it. I found out mine was made 6/17/1989 and it now sports a B square mount you could of bought back in that time. I have also added a trs25 and have been using it as my target gun for almost a year now. Its a great gun. though in spite of what i paid.
