Here We Talk About Military Light Weapons From Every Country, From Every Era, From Every Ammunition Type, From Bullets To Rockets.
The G36K ('K' for Kurz or Short) is basically a G36 with a shorter barrel and hand guard, it's also provided with a flash suppressor which differs from the one of the main G36 model.
Note that the pictured G36K haves a different carrying handle (with Picatinny rail and iron sights), the stock is also folded.
