H&K's English sales brochure for the G11 caseless weapon-ammunition system, with the Sterling, Virginia address (print code read as 10.88). Cited by the Hyper-Burst Mechanisms dive for the G11's specifications and by the Daisy dive for its 450 rpm figure.
GESELLSCHAFT FUR U LOSE GEWEHRSYSTEME MBH [ee eer Weapon-Ammunition-System with caseless ammunition Digitized by: SMALL ARMS |i. SMALLARMSOFTHEWORLD.COM G 11 — the new weapon-ammunition-system with caseless ammunition for high hit probability. This new technology has, for the first time, provided a solution meeting the tough demands of a modern battlefield. The G11 Rifle with caseless ammunition sets new standards @ High hit probability even under combat conditions @ Quick readiness to fire @ Maximum reliability under all environmental conditions @ No impeding recoil effect on the shooter @ Low system weight @ Compact form @ No ejected cases @ Simple care and maintenance @ Short training times for users @ Small cartridge dimensions @ Low cartridge weight @ Large number of rounds can be carried The caseless ammunition The propellant body of the caseless round has a quadratic cross-section, thus avoiding unused space in packages and magazines. In order to achieve optimum exterior and terminal ballistic performances, the projectile combines an extremely slim ogive shape with a high sectional density. The effect on soft targets is in accordance with international conventions. Even at short ranges the round does not fragment in the soft target medium. Penetration capability through steel and concrete is comparable with conventional ammunition of larger calibre. The penetration performance against hard targets is so high that a German steel helmet (NATO test standard) is penetrated with a soft core bullet at ranges up to 600 m. Ballistic table Ammunition packaging The water-tight ammunition pack doubles as the reloading unit. These reloading units are so small that they can be stowed almost anywhere. The caseless ammunition is absolutely safe. In the absence of a case no overpressure can be generated by exposure to fire or bullet impact. The risk of cook-off is largely eliminated by the extremely high self-ignition temperature of the propellant.

When firing sustained fire the subsequent shot is automatically fired as soon as this forward motion is completed. Due to the well Sustained fire 130 ms = 460 rds/min _ 3-round burst ._ _ 60 ms = 2000 rds/min —— absorbed recoil impulse it is for the first time possible to deliver aimed sustained fire. Firing a 3-round burst drives the floating system during all 3 firing cycles to the rear with increasing speed. The third bullet has already left the barrel before the recoil is felt by the shooter. Sustained fire The cylindrical breech The completely new cylindrical breech design allows a rate of fire in excess of 2000 rounds/minute in the 3-round burst mode. This high cadence is only possible because of the short, absolutely straight cartridge feed into the vertically positioned chamber. The cylinder with the chamber carrying the cartridge is then rotated 90° into the firing position. The cartridge is mechanically ignited. The propellant gas drive rotates the cylinder back into the feeding position, the next cartridge is chambered and the cylinder tilted again into the firing position. G 11 Rifle with Orion 80 night sighting optics. The sight The well protected optical sighting system and sight adjustment elements are Y Feed direction Cylinder in feed position Cylinder in firing position The receiver All moving parts of the G 11 are protected in a completely sealed receiver. This not only guarantees operation under adverse conditions, but also considerably simplifies care, maintenance and logistics. The G 11 remains fully functional under all climatic and operational conditions. 3 integrated into the rifle’s removable carrying handle. The optical sight with its 1:1 magnification allows rapid target acquisition. At the same time it allows full observation of the battlefield with binocular vision without tiring the eyes. All materials are chosen to resist corrosion, wear, NBC war influences as well as all kinds of chemical substances. Visible light and IR light reflection is reduced to a minimum. The smooth surface facilitates easy decontamination. Combat analyses show that conventional rifles achieve only low hit rates. Physical fatigue, target motion, battle noises, enemy fire, etc. handicap the gunner when he tries to properly aim his rifle. The G 11 achieves its high hit probability by firing automatically limited three- round bursts with defined dispersion! This weapon dispersion does not depend upon the shooter or his training level. “UML mI eu makes a total of | makes a total of ) makes a total of tote 5iO car tridges DAC (orslaia idges 100 eal triages available to Vailable to thi a cB 16.2 Ibs. 16.2 Ibs. 16.2 Ibs. soldiel \Well fle 0 ps Hit probability Despite aiming and lead angle errors the 3-round burst with its defined dispersion increases hit probability considerably and thus also reduces ammunition consumption.
