Knife bayonet for use with the 5.56 mm. NATO caliber Sturmgewehr 90, a variant of the S.I.G. 550 assault rifle. Stgw. 90 production began in 1986, eventually superseding the renowned Stgw. 57 by the mid-1990s. Like its predecessor, the Stgw. 90 quickly garnered a reputation as one of the finest rifles in its class. Stgw. 90 bayonets may be found with either Victorinox or Wenger maker marks. A solid, utilitarian bayonet, the edge is ground on one side only, the opposite side of the blade being flat. The hilt has green plastic grip scales and a sliding spring catch similar to that used on the Stgw. 57 bayonet (so similar that the Stgw. 57 bayonet will reportedly mount on the Stgw. 90 rifle). The scabbard body is olive green plastic with a frog loop on the blackened steel throatpiece. Take a good look at the photos, they are part of the description. See the clear photos for an impression.
