H&K G36K.

The 5.56 mm G36K (K for “Kurz” or short) is the carbine variant of the G36 and possess all the features of the full length G36 rifle but is equipped with a shortened 12.5 inch (318 mm) barrel and abbreviated handguard. With the buttstock folded the G36K measures just 24.21 inches (615 mm) overall, making in handy in confined spaces like inside a vehicle. Developed by HK in the mid-1990s, the 5.56mm G36 is a true modular weapon system made almost entirely of a tough, carbon-fiber reinforced-polymer and uses a simple, clean-shooting, self-regulating operating rod gas system. A lightweight weapon, the G36 can be configured as a rifle, compact carbine, carbine, or light support variant that delivers high performance with extremely low maintenance Exhaustively tested and currently fielded with the German, Spanish, and Greek Armed Forces, the G36 is also used by many international law enforcement agencies and other military customers. The rifle variants of the G36 use 18.9 inch (480 mm) chrome-plated specialty steel barrels, manufactured using HK’s proprietary cold hammer forging process for long service life and accuracy. The main weapon components (receiver, trigger group, buttstock, handguard and carrying handle) are made of corrosion-proof polymer with stainless steel inserts. This keeps weight low without sacrificing strength, durability, or robustness. Magazines are also made of translucent high-strength polymer and lock together without a magazine clamp. The G36 gas system does not direct fouling back into the weapon’s interior like conventional gas operated rifles. This insures reliable operation even after firing thousands rounds without cleaning. The polymer components can easily be cleaned with water-based cleaning solutions, or even water. A variety of sighting systems, including the Dual Combat Sight (combined electronic “red dot” reflex and optical 3 power telescopic) can be installed directly on the top of the G36 receiver. A Picatinny-type rail system can also be mounted on the receiver to accommodate virtually any accessory optic or mechanical sight.
