We like this configuration for shooters who want an AR rifle with its optic and core range accessories included. The free-floating handguard provides M-LOK mounting space, while the threaded barrel and included flash hider-compensator support the stated muzzle configuration. Rose gold controls, a rose-engraved handguard, and the reduced-angle grip give the rifle its distinct appearance without changing the familiar AR layout. The SIG SAUER M400 ROSE brings those design choices together in one complete package.
