gas block

Can anyone ID this gas block? It is stainless and is marked with what appears to be capital block letters “H A “ with a round symbol between them or possibly “H O A” with the “O” as part of a logo? This is the only pic that I have and it has been enlarged and cropped so is very grainy. Thanks!

Bought from Operation Parts. Same as new condition. Absolutely perfect. Very solid and extremely well machined. .750 bore. Also, made in the U S A by PRI. Cost $ $190.00 new. Id like to get $135.00. Still need funds for my RECCE build. Thanks for looking.
