Is there an upper to fire .45 in an AR-15?

[HouTex]

I am interested in doing this if it is available and reliable. Any info would be greatly appreciated.

You might check with Olympic Arms in Washington I think. If I remember right I think they made uppers in .45.

Dalphon uppers are just Oly Arms uppers in a different box.
