This video provides an in-depth look at a custom HK XM8 build by TommyBuilt Tactical, featuring authentic XM8 components integrated with G36 parts. Larry Vickers details the XM8's history within the OICW program, its intended role to replace the M4/M16, and its advanced modularity. The review highlights ergonomic improvements over the G36, the innovative Insight Technologies Integrated Sight Module, and the unique PCAP attachment system, while also touching on the reasons for its eventual cancellation.
This video explores a non-functional mockup of the XM29 OICW, a 1990s US military program aiming to consolidate the M16, M4, and M203 into a single weapon. It featured a 5.56mm rifle and a 20mm smart grenade launcher with programmable detonation. The program ultimately failed due to excessive weight and complexity, though its rifle component influenced the HK XM8.
