In the 1990's SOCOM establishes the SOPMOD program. This program is implemented by NSWC. Fruits of this program include the SOPMOD buttstock and the CQBR.
NSWC develops an enhanced SOPMOD buttstock based on the ACR buttstock. Unlike the ACR buttstock it is compatible with the standard M4 receiver extension and has storage available for batteries.
NSWC develops a CQBR. This consists of taking a M4A1, chopping the barrel back to 10.3", opening the gas port to .070", adding a BUIS, a KAC M4A1 QD Compensator and RIS. This is available starting in 2000 through the SOPMOD program and assigned the temporary NSN: 1005-LL-L99-5996. Those built during the 2000-2002 time frame had the CAF forge code, handguard caps have M203 clearance cuts, and the FSB's are marked "F". Also available was the SOPMOD buttstock. For a BUIS the standard SOPMOD 300M KAC or Chopped M4/A1 carry handle is used. These are used by various units, the most visible being SEAL teams.
It appears that the CQBR was dropped from the SOPMOD program, while US Navy demand exceeds NSWC production capacity. In response the project is largely farmed out in 2004, and the MK18 MOD 0 is born. The MK18's biggest users appear to be US Navy VBSS teams, and US Navy EOD.
After a small in house run (500?) LMT is provided the TDP and a license agreement for Mr. Armstrong's SOPMOD buttstock and production begins in 2004. It is a favorable agreement for LMT in that they are allowed to sell the buttstock on the open market. NSWC buttstock production ceases, and LMT buttstocks are now used.
NSWC supplies Colt with the RIS, vertical grip, QD comp, O-ring, and LMT buttstocks & rear sights. Colt installs this hardware on the Carbine (QD with crush washer). Carbines are to meet the same specs as the M4A1 Carbine (less the endurance test) MIL-C-71186. These carbines are offered by NSWC as NSN 1005-01-527-2288. In addition to complete carbines supplied by Colt NSWC builds complete MK18's using the above mentioned Colt uppers on refurb older lowers with the LMT buttstock that are engraved MK18.
