Heckler & Koch XM29 Objective Individual Combat Weapon

The XM29 OICW or SABR ("Selectable Assault Battle Rifle") was an attempt to produce a next-generation hybrid firearm which would combine a "smart" airbursting grenade launcher (a bullpup design based loosely on the Heckler & Koch CAWS shotgun) with a 5.56mm rifle, with the aim of at least partially replacing the M16 rifle, Colt M4 carbine, and M203 grenade launcher. The project began in the 90s as part of the US military's SAMP (Small Arms Master Plan) weapon series, and ran until 2005 when it was cancelled due to failure to meet weight goals; during that time a bewildering array of prototypes and mock-ups were produced, of which the first image to the right is the most widely recognized; this version was produced by Heckler & Koch and Alliant Techsystems Inc. Following cancellation, the program was split into three 'increments;' the first being the development of a new family of lightweight kinetic energy weapons, the second the development of a standalone grenade launcher using the technology that would have been used in the original OICW, and the third the re-integration of the two into a single device.
During the course of the project the 20mm HE module was changed to 25mm due to concerns over the performance of the 20mm projectiles (the 20x28mm round had little propellant for effective direct-fire munitions and a large part of the body of the HEAB projectile was taken up by electronics for the programmable fuze); after the cancellation of the main project, this became the 'increment two' Heckler & Koch XM25 program; this weapon, following field trials, was ultimately defunded as a project (though the concept may continue to be developed further). The Heckler & Koch XM8 was developed in an attempt to meet the requirements of OICW increment one, but this was later cancelled; it is not presently clear if the LSAT program that replaced it is intended to become OICW increment one, though most commentators agree the OICW program is effectively dead.
The underbarrel "kinetic energy module" was a compact carbine rifle based on the Heckler & Koch G36 with some variants using a barrel just 9.8 inches long, though one planned configuration instead used an underbarrel SMG which would later become the Heckler & Koch MP7.
