The HK SL8 sniper rifle is a rifle used by Stargate Command. In 2003, Col. O'Neill borrowed one from Penhall to cover the rescue of Rya'c and Bra'tac on Erebus. (SG1: "Orpheus")


  • Though called a HK SL8 sniper rifle in Stargate SG-1: The Ultimate Visual Guide, the actual weapon shown is an H&K G3/SG-1 sniper rifle, an accurized and purpose-built variant of the Heckler & Koch G3 battle rifle.
  • Though there is indeed a real HK SL8, it looks nothing like the PSG-1. It is a "civilianized" variant of the 5.56 x 45 mm NATO G36K, with a gray polymer chassis, a 10-round single-column magazine, and a thumbhole stock instead of a pistol grip. An actual SL8 can be seen in the hands of an SG-15 member before their ultimately scrubbed mission to determine the location of the Aschen homeworld. (SG1: "2001")
