This SIG Sauer M400 Forge is a 5.56 NATO AR-15 (SIG Sauer part no. RM400556N16BFORGECA) built in a California-compliant configuration without giving up the ROMEO-MSR optic that makes the Forge line ready to shoot out of the case. It runs a 16-inch barrel finished in black with a 1:7-inch twist rate for stabilizing a wide range of 5.56 loads, and feeds from a 10-round magazine to meet California’s capacity rules. Built on a semi-automatic AR platform, this configuration weighs approximately 9.7 lbs and gives California shooters the same accuracy and reliability SIG built into the standard M400 Forge. It’s a strong option for range use or home defense for shooters who need a fully compliant build.
