Its performance is only slightly hampered by the damaged sights: The upper right side of the bent front sight is where the rounds will land. It offers considerable firepower, good accuracy, acceptable action point cost in VATS and a high rate of fire in regular combat. The unique service rifle is an excellent general purpose weapon effective at all but the longest ranges. The Survivalist never fixed it, adapting to using it bent. Its front sights were bent out of position during one of his many combat encounters in the canyon. Lacking gunsmithing skills, he repaired damage by jury-rigging the rifle, replacing damaged wooden parts with furniture salvaged from other weapons and binding it with metal clamps. Carrying it with him on the way home, to Salt Lake City, it became his closest friend after the city was obliterated by nuclear fire and he sought refuge in Zion.

It was used by Randall Clark, a United States Army veteran who was stationed on the Canadian front and witnessed atrocities carried out in the name of the Stars and Stripes first-hand.

In fact, it was assembled and issued from Long Branch Arsenal in Toronto, Ontario, forcibly annexed as a USA territory. This particular rifle was issued to occupation troops stationed in Canada, where resistance fighters remained a constant threat to military operations. It offers good ballistic performance, firepower, and penetration at range, making it ideal for eliminating threats that would otherwise prove resistant to standard-issue 5.56mm or high velocity 5mm rounds. The standard service rifle barrel was replaced with a shorter, more maneuverable one, while the chamber and magazine well were modified to accept a larger caliber ammunition: The 12.7mm cartridge. This rifle is a special-purpose weapon designed for use by personnel requiring an accurate, high-powered weapon with excellent penetration, such as checkpoint guards.
