Abstract (en)
[origin: WO2017220348A1] The invention relates to a weapon barrel (30) having a land/groove profile (20) having lands (25) and grooves (26) for highly stressed weapons, wherein the height (h) of the lands (25) decreases towards the flanks (25.3, 25.4) of the lands (25) by an amount (29). As a result, the surface (O') of the lands (25) is formed by two surfaces (25.1, 25.2) which lie at an obtuse angle relative to one another or enclose an obtuse angle.
