4sevnty - As you know, forend loops are traditionally soldered directly onto the bottom rib, and in theory can separate from the ribs. Personally, I’ve only seen this happen (first-hand) once, and it was on another brand of rifle.

The forend loop on the HEYM is not assembled this way. I've got a photo somewhere around here, but I'll try to explain it verbally.

The forend loop on the HEYM has an extension (made in the shape of an hour glass) that extends up and between the barrels. The outside contour of the barrels mate with the concave sides of the extension on the loop and create a mechanical lock that prevents the loop from moving.

When you look at the loop on the underside of the barrels, it looks like it is simply soldered to the bottom rib, but hidden underneath is a mechanical lock between the barrels and the extension on the loop.

You could probably use a pair of pliars and break the steel by bending the loop back and forth, but you can not pull it off.

I too have been told that the Deely release is inferior in some way(s). Both personally and professionally speaking, but I've never had a problem with one.
