During the early stages of research and development in the mid-1990 one out of the two teams was selected as a winner for further development contract. This team is lead by the US based Alliant Techsystems corporation (ATK), with the Heckler&Koch, Brashear and the Omega companies as the other team members. The ATK is responsible for system integration, and also develops the 20mm munitions; H&K is responsible for both the 5.56mm rifle and the 20mm grenade launcher; Brashear works on the sighting equipment and Omega provides the training means. The resulting weapon was type-classified by the US Army as the XM-29, and is scheduled to enter the service during the year 2009 in limited numbers. It will be then consequently upgraded with the new technologies then available. Present plans for fielding the M29 are to issue four units per one infantry squad of 9 men. Early in the 2002 the XM-29 test weapons were successfully tested with the newest 20mm HEAB (High Explosive Air Bursting) munitions, which will be a major "kill factor" for the M29 weapon. At the same time the "kinetic energy" part of the XM-29 was type-classified as the XM-8 light rifle, and, in the near future, could possibly  replace the current M4A1 carbines as a standalone compact conventional small arms.

  "The Small Arms Master Plan" (SAMP), requested for a family of infantry "Objective" weapons, namely the Objective Individual Combat Weapon (OICW), Objective Personal Defense Weapon (OPDW), and the Objective Crew Served Weapon (OCSW). The SAMP stated that such weapons must utilize the latest developments in computers and visual technologies, as well as in the small arms, and combine both high explosive warheads and traditional bullets fire capabilities in a single weapon, that should be fielded circa 2000. Of cause, the timelines and most of the weight and cost requirements set in this paper looked unrealistic from the start, but the development of the Objective weapons began in the early 1990s. The XM-29 is a combination weapon, which has the 20mm semi-automatic, magazine fed grenade launcher as its primary part, and the 5.56mm compact assault rifle as its secondary part. Both parts are assembled into the single one-man portable unit, with the addition of the target acquisition / fire control system (TA/FCS), which is an essential part of the whole system. The XM-29 will become an integral part of the future Land Warrior system, capable of communicating with the other parts of this system, including the tactical computers and helmet-mounted displays. 
       
  The grenade launcher is capable to fire in semi-automatic mode only, and is gas operated. It has a bullpup layout with the detachable box magazine located in the butt of the weapon. In the standard configuration most of the fire controls for the grenade launcher part are located on the rifle part, including the single trigger for both firing modules. The launcher has the provisions for the TA/FCS system to be mounted on its top, and the appropriate interfaces, so the data provided from the TA/FCS can be used to program the 20mm grenade fuses.

The rifle part of the XM-29 system, on the other hand, is a fairy conventional, short-barreled assault rifle, derived from the H&K G36K assault rifle. The basic "rifle" part of the XM-29 has no buttstock and no own sights, and thus can be used separately from the whole system only as emergency, personal defense weapon. While being mounted to the whole system, it can be used for a close quarters work, both defensive or offensive, or as an low-cost, low intensity medium range offensive weapon. Most of the XM-29 system controls are built into the "rifle" part, around the trigger guard.

M29 SABR OICW
     
  GAME DATA: M29 SABR

The H&K M29 is an OICW. It' main function is to shoot 20mm grenades at enemy positions and the XM8 is there to keep enemis away from you. Good at long ranges and fairly good at close range. Not the best weapon for quick shoot outs, since the grenade launcer takes some time to get operational. 1X-6X zoom gives it a good range and the night vision helps in those dark places.
The weapon is just a prototype, so no one else has it yet.
