Heckler and Koch - Manufacturers - Top Gun Supply

The SP5 was developed by Heckler & Koch as a semiautomatic, civilian sporting pistol that matches the look and feel of the legendary MP5 submachine gun.

Designed and manufactured to meet the definition of a civilian pistol, the SP5 is loaded with authentic features, like a Navy barrel with threaded tri-lug adaptor, paddle magazine release, fluted chamber and chrome-lined bore. This is equipped with an 8.86" barrel and its overall length is just 17.8".

The backbone of the SP5 is the roller-delayed blowback operating system, which is legendary for its accuracy, reliability, and smooth shooting dynamic. Originally perfected on the Heckler & Koch G3 rifle, it has been used on several other HK firearms still serving today around the world.

The SP5 is manufactured in Heckler & Koch’s Oberndorf factory in southwest Germany. It retains many of the critical elements of the MP5, including its precision-machined components and attention to detail. This high level of quality and workmanship is a result of making the SP5 in the same factory, on the same lines, and by the same workforce that has been making MP5s for years.

For more comfortable shooting, the SP5 is equipped with an elastic “bungee” sling. The sling is easily installed by snapping it onto the sling swivel hardware located on the rear of the receiver. Using the sling makes firing the SP5 more stable and reduces fatigue. Also ships with two 30rnd magazines.

The long awaited commercial variant of the MP5k smg, the HK SP5K is completely identical to the MP5k with the exception of the mandatory statutory changes inside. In particular, the interfaces for magazine, buttstock/receiver cap, handguard and sight mount are all identical to the MP5k. A true state of the art weapon system, the SP5K features a quick release Picatinny mounting rail, slim line handguard with HKey mounting slots, ambidextrous fire controls and available buttstocks for those who want to make the weapon an SBR. The SP5K can be universally used both as a pistol or a shoulder-mounted weapon with proper paperwork. Includes hard case, sling, and two magazines.

A direct descendent of the HK416, the MR556A1 is a semi-automatic rifle developed by Heckler & Koch as a premium level commercial/civilian firearm with match rifle capability. Like the HK416, the MR556A1 is a major product improvement over conventional AR-type carbines and rifles. The Heckler & Koch MR556A1 uses the HK proprietary gas piston operating system, employing a piston and a solid operating “pusher” rod in place of the gas tube normally found in AR15/M16/M4-style firearms. This method of operation virtually eliminates malfunctions that are common to direct impingement gas systems since hot carbon fouling and waste gases do not enter the receiver area. This is the same key feature critical to the success of the HK416 rifles used by leading military and law enforcement customers

This is the same key feature critical to the success of the HK416 rifles used by leading military and law enforcement customers. The MR556 Competition model features input from competitive shooters and is designed for enhanced performance in a competitive or duty environment. Features a 14" Modular keymod rail system, lightweight Magpul CTR stock, muzzle brake, oversized, extended magazine release, extended charging handle, two stage trigger, and cold hammer forged 16.5" barrel.

Taking an essentially standard MR762A1 (caliber 7.62 x 51 mm NATO) semi- automatic rifle, Heckler & Koch USA turns it into a more effective precision rifle by an astute addition of the right optics and accessories. A Leupold 3-9VX-R Patrol 3-9 x 40 mm scope and mount, HK G28 adjustable cheekpiece buttstock, and LaRue Tactical BRM-S bipod are the primary add-ons that make the MR762A1 Long Rifle Package (LRP) more than a sum of parts.The MR762A1 LRP uses a barrel produced by Heckler & Koch’s famous cold hammer forging process. The highest quality steel is used in this manufacturing process, producing a long-life barrel that provides superior performance with minimal degradation of accuracy and muzzle velocity after prolonged use. The barrels are manufactured in Germany and finished in the USA.

Additional accessories and add-ons for the LRP variant of the MR762A1 include an ERGO Pistol Grip from Falcon Industries, the same Blue Force Gear sling used on the HK M27 IAR supplied to the USMC, and an OTIS cleaning kit. The rifle package, complete with one 20 and one 10-round magazine is shipped ready to use with the scope attached in a compact 42-inch Model 1720 Pelican case.

The HK MR762 has been engineered based on the HK417 design, but in a semi-automatic configuration for civiliam use. The MR762 uses the HK Gas Piston System, consisting of a piston and operating rod which reduces wear and carbon fouling. This increases reliability over gas impingement systems. The MR 762 comes standard with ambidextrous controls, free floating Modular Rail System (MRS), and a two stage trigger.
