CMMG machines their front sight base assembly to mil-spec dimensions for a reliable fit on standard barrel journals. The F-marked designation means the sight is calibrated for use with a flat-top upper receiver, compensating for the shorter distance between the front and rear sight planes compared to an A1-height front sight. In addition, the F-marked front sight base provides the correct elevation reference when used with a standard A2 or flat-top rear sight. Furthermore, the assembly includes all hardware for installation on a standard AR-15 upper receiver with a pinned front sight configuration. Also, the standard front sight post accepts any mil-spec post for replacement or adjustment. When you need a reliable F-marked front sight base that gives you accurate iron sight alignment, this CMMG front sight gas block is a practical replacement or build option.
