Notes: Imported from Germany and sold exclusively though ATI, the GSG-5 (German Sport Gun) is sort of an MP-5/HK-94 chambered for .22 Long Rifle instead of 9mm Parabellum. The barrel has been extended to 16.25 inches, and most of this extended length is surrounded by a faux silencer to protect the long, narrow barrel. Most of the GSG-5 looks virtually identical to the MP-5, though the shape of the pistol grip, trigger, and trigger guard are different, as is the trigger unit. The ejection port is also much smaller than that of the MP-5. The magazines are of the same dimensions as those of a standard MP-5, but they have clear windows in the sides allowing the shooter to see his ammunition supply; they also hold 22 rounds instead of 30. (10 and 20-round magazines are also available.) A clamp is available to allow two magazines to be clipped together. Sights are essentially the same as those found on the MP-5, adjusted for the different ammunition chambering. The standard MP-5 safeties are present, and the GSG-5 also adds a magazine safety. The GSG-5 can be had with a fixed or folding stock; again, these stock are virtually identical to those of the MP-5.
