"I don't think there are any intentional "assisted" openers. Most of them are by products of the action's cocking mechanism or the ejector work."
I disagree. My CSMC RBL has a seperate mechanisim for assisted opening. It is a plunger-type compression spring devise that is mounted on the underside of the barrels and covered by the fore arm. When the opening lever is operated the assisted opener spring "Pushes" the action open while cocking the hammers. The action is a little harder to close.
The CSMC RBL assisted opener can be removed from the gun.
