Broadwell Ring

The Broadwell Ring is a small ring found in French and German firearms. It sits in a recess in the end of the bore, and abuts against a flat plate. When the gun is fired, the rapidly expanding gases produced by the combustion of gunpowder force the Broadwell Ring against the plate, sealing the end of the bore against escape and directing the full force of the explosion toward propelling the bullet.
