Background

This device is for clearing trip-wire type land mines.  It can be fired one time using the standard rifle spigot using normal ball ammunition and multiple times using blanks.  The patent goes into some length differentiating this from other muzzle launched devices such as rifle grenades (Wiki), harpoons (Wiki), line thrower (Wiki, my antennas web page), ropes &Etc.

This may have an application for launching an antenna wire.  But the snags would need to be removed first.

Made by SAA International (out of business as of 2017?; Archive.org product web page) a sister company to Critical Solutions International (Route Clearance).

Description

A Grappling hook (Wiki) is similar in shape to a fishing hook, except it's larger and designed to grab onto something either to retrieve the item or to act as an anchor.

This unit includes a bullet trap and claims maximum range of 75 to 100 meters with 5.56 mm ball ammunition. It can only be fired one time with ball ammo, but up to 20 times using blank ammo, but with decreased (unspecified) range for practice.

FM 3-34.2 Combined Arms Breaching Operations (on line) paragraph C-57 talks about manual and weapon launched grapnels.

Weapon-launched. A 150-meter lightweight rope is attached to a lightweight grapnel that is designed to be fired from an M16A1 or M16A2 rifle using an M855 (Wiki) cartridge. The grapnel is pushed onto the rifle muzzle with the opening of the retrieval-rope bag oriented toward the minefield. The firer is located 25 meters from the minefield’s leading edge and aims the rifle muzzle at a 30- to 40-degree angle for maximum range. Once fired, the grapnel travels 75 to 100 meters from the firer’s position. After the Weapon-Launched Grapnel Hook (WLGH) has been fired, the firer secures the rope, moves 60 meters from the minefield, moves into a prone position, and begins to grapple. The WLGH can be used only once to clear a minefield, but it can be reused up to 20 times for training because blanks (Wiki: M200, M755?) are used to fire it.
