Who has a tapered five inch

Clark scope rail besides Clark himself. His website seems to be poo poo right now.

More info needed.

Clark Custom Guns makes a four hole weaver style scope mount for most 45 ACP handguns. It has a slight taper cut into the length with the ejection port already milled.

I had no problem with their site. Sorry don't have a 1911 mount anymore. I don't remember them being tapered.

Skip it Gents,
As it turns out after my fourth attempt to "check out " what the site wanted was not only a street address but an apartment number ? I added the word front building to the list and it allowed me to check out, order accepted.

Go figure
