MP5 submachine gun
Heckler & Koch MP5 submachine guns employ the same delayed blowback operated roller-locked bolt system found in the famous HK G3 Automatic Rifle. All the elements of HK excellence; reliability, ease of handling, simple maintenance, and safety are highlighted on the MP5. Firing from the closed-bolt position during all modes of fire makes MP5 submachine guns extremely accurate and controllable.

Used by military and law enforcement units in more than fifty nations, the MP5 is firmly established as the world’s preeminent submachine gun. Over 120 variants of the HK MP5 submachine gun are available to address the widest range of tactical requirements. A selection of optional trigger groups allow for single fire only, full automatic, 2-round, and 3-round burst options. The weapon’s unique modular design and a variety of optional buttstocks, forearms, sight mounts, and other accessories gives the MP5 extraordinary flexibility to meet most any mission requirement.
MP5SFA2 9mm with single fire trigger group.
MP5SF
The MP5SF (single fire) carbine is a semi-automatic only variant of the MP5 fitted with a trigger group that prevents full automatic firing. The Single Fire (SF) trigger group can be replaced with other MP5 trigger groups to allow burst and full automatic firing.

The MP5 Single Fire is an ideal squad car carbine. It is an excellent supplement or replacement for a police shotgun. It has less recoil, greater range, and more ammunition capacity than a shotgun and is especially suitable for small stature officers.

MP5K
The MP5K is the ultimate close quarters weapon. At 4.4 pounds and less than 13 inches long, the MP5K is easily concealed and carried. All MP5Ks can be fitted with an optional folding buttstock. The MP5K can also be fired from inside a specially designed briefcase.

with Navy trigger group.
MP5K-PDW
The MP5K-PDW is a compact submachine gun designed for vehicle operators, air crew members, security details, and others who require a small, but powerful weapon. While comparable in performance to full size MP5s, the size and weight of the MP5K-PDW make this weapon the ideal choice where a rifle or full-sized submachine gun is unmanageable and a handgun is a poor compromise. With its sturdy folding buttstock and threaded barrel the MP5K-PDW is an exceptionally flexible weapon.
MP5SD3 9mm with integral aluminum sound suppressor
and standard"SEF" trigger group. NSN: 1005-01-144-3036
MP5SD
For specialized applications requiring fully realized sound and flash suppression, several MP5SD models are available. The removable sound suppressor is integrated into the weapon’s design and conforms to the normal length and profile of a conventional, unsuppressed submachine gun. The MP5SD uses an integral aluminum or optional wet technology stainless steel sound suppressor. It does not require use of subsonic ammunition for effective sound reduction like most conventional sound suppressed submachine guns.

Common throughout each weapon group is the ability to use many interchangeable assembly groups and components. This provides the ability to train personnel within one weapon group and have them competent with the entire weapon system.

Accessory claw-lock scope mount and telescopic sight. HK scope mounts attach to rifles and submachine guns without tools at special points that ensure 100% return to zero. HK scope mounts do not interfere with the use of the weapon’s iron sights .
MP5/40A2 .40 S&W with 3-round burst trigger group.
MP5/10A3 10mm Auto with 2-round burst trigger group
and optional stainless steel screw-on sound suppressor.
MP5/40 and MP5/10
The MP5/40 and MP5/10 are product improved variants of the 9mm MP5 chambered for the more powerful .40 S&W and 10mm Auto cartridges. Although the operation and functioning principles of the MP5/40 and MP5/10 are identical to the 9mm MP5, several user inspired improvements have been incorporated into the design, including a new bolt catch device that holds the bolt group rearward after the magazine is empty. Depressing the bolt catch releases the bolt to chamber the first round of a loaded magazine.New lightweight synthetic magazines are durable and ensure reliable feeding under the most extreme conditions. Like all MP5s, the MP5/40 and MP5/10 can be disassembled without tools for cleaning and maintenance.

The firepower, penetration, and hard-hitting potential of a 10mm MP5 is greater than a .45 ACP Thompson submachine gun. At any range, the projectile fired from a 10mm MP5 has nearly twice the energy of a comparable 9mm, .40 S&W, or .45 ACP cartridge. In 1994, the U.S. Federal Bureau of Investigation (FBI) adopted the MP5/10 as their new submachine gun.
