That should fit in theory, but the problem with dovetails is that the tolerances have to be really tight, or the rail won't clamp at all. Let's say the slot cut in the asa is a little on the small size, (but within tolerances) and the rail's dovetails were also cut a little too big (also within tolerances) than there's a chance that they won't fit. Also anodising adds a few mills to the dimensions.
If you have a vise nearby, you could try to bend the rail's dovetails slightly inwards... Remove the set screws, and use something to protect the surface of the rail (a few strips of aluminum will do) and give it a slight bend... Not too much though, you only need a few thou to make it fit.
being in battle! I love the moment when my marker stops being a machine and becomes part of me! My blood boils
and my mind goes all white!
It's an incredible high!
There's no time to think, only action!
