Since I'm new to the forum, I thought I would start something of my own. Not only as a reference to others who have this rifle or are thinking of getting one, but also for myself since I can't remember anything anymore.
With my tax return this year I purchased a used PTR-91 SC
It came in this case from an FFL in Ohio. Though it was advertised to come with six magazines, it arrived with 8. Who am I to complain? It went well with the 5 that I ordered before I bought the rifle (just in case the "high capacity" ban went into effect early)
From what I could tell it was maybe fired a couple times at most. The spring was still super stiff and there were no scrapes or scratches on it.
