I bought one of the swinger targets last year for 22 shooting. The target seems to be fine but the similar material bracket/spindle was not worth a penny. It was meant to hang from a 2" lumber backstop or frame but was so flimsy, it wouldn't hold it's shape and therefore, would not allow the target to swing. After a weekend of use, I took it apart and haven't modified it to work better(yet). I'd look at one with a metal frame rather than the one I got.
My son and I have been contemplating buying one of the 12 packs from CTD since it's a lot cheaper on a per target basis.
