Ohio deer rifle rebuild

[dgodii]

Backstory on this odd 5.56 rifle is I bought it when stationed in California years ago. Then dropped it off back home to family in PA and continued traveling the world. Apparently they loved it for poppin deer over the years. When I came back to the US last year and shot it for the first time, I could only get 1 foot groups at 50 yards.

Recently rebarreled with an American barrel at LMG Firearms. Can anybody here identify this odd rifle?
