MP5
The MP5 and its many variations are produced by the German firm
Heckler & Koch. The Heckler and Koch MP5 Submachine gun is a
lightweight, air-cooled, magazine-fed, delayed blowback operated,
select-fire weapon that can be shouldered or hand fired. The
H&K MP5 submachine gun is chambered for various pistol
cartridges to include 9x19mm Luger, .40 S&W, and 10mm Auto. It
fires from a closed-bolt position in semi-automatic, 2 or 3-round
burst, and sustained fire modes. The weapon utilizes the unique
H&K roller-locked bolt system used commonly throughout the
H&K family of small arms. The unique features of the H&K
MP5 submachine gun include a free floating cold hammer-forged
barrel, stamped sheet steel receiver, fluted chamber, straight-line
stock and a pistol grip with ambidextrous safety/selector lever.
The bare metal surfaces of the MP5 are phosphated and coated with a
black lacquer paint. This dry lacquer coating is applied with a
magnetic charge and then baked onto the metal in an oven. The
resulting finish is highly resistant to salt water corrosion and
surface wear.
