Does Oly style uppers work with both a lower with a top-loading Hahn block with Promags?

I might have a line on a pistol upper from Olympic Arms, but need to know if it will work with a Hahn block using Promag style mags.

I'm not 100% sure, but I don't think so.

Why do you want to use a Hahn block?

In an Oly system, the mag is foreward in the magwell where as in the Colt system the mag is in the middle of the magwell. The blocks for the Colt have feedramps, where-as the Oly does have. The chambers and barrels are a bit different also.

Aren't the Hahn blocks stritcly for a Colt/RRA system?

Hahn makes adapters for both Oly and Colt systems.

Magazines do not interchage between the two uppers......Oly=single feed.......Colt=double feed.
