Description


Introduction

The HK 512 is a semi-automatic shotgun of Italian origin. It was developed and produced by Franchi at the request of Heckler & Koch, which took care of marketing and sales. The HK 512 was one of the first semi-automatic shotguns developed for law enforcement use. The mechanism was later employed in the very successful Super 90 series developed by Benelli.

Design

The HK 512 is a semi-automatic shotgun that uses a H&K recoil system that is also found in the later Benelli Super 90 series. The stock and forearm are made of wood and the rest of the gun is made out of metal. The smoothbore barrel is fitted with a choke that acts as a shot diverter.

Firepower

The HK 512 is a semi-automatic shotgun that fires 12ga 2.75-inch shotgun shells. The tubular magazine holds 7 rounds. Only buckshot can be fired due to the muzzle device that shapes the shot horizontally in an oval pattern. The mechanism will not cycle low powered rounds

Users

The HK 512 was relatively successful and was adopted by various law enforcement and counter terrorist units. Due to its age most have been replaced by newer designs.
