This M400 ROSE features a 16-inch chrome-moly steel barrel with a threaded muzzle and a rose-gold colored slotted flash-hider/compensator. The 1:7 twist supports common 5.56 NATO bullet weights, and the mid-length gas system is paired with a free-float design for consistent operation.
The ROSE theme is applied at the factory, with ROSE script and a rose graphic engraved on the aluminum M-LOK handguard. Controls including the safety selector, bolt catch/release, magazine release, trigger, and forward-assist cap receive a matte rose-gold finish. An ambidextrous bolt catch is included for practical handling.
The upper is a flat-top receiver with a Picatinny rail; the handguard is a slick M-LOK design with no 12 o’clock top rail. The rifle ships without iron sights. The handguard is aluminum and free-floated for accessory mounting via M-LOK slots. The lower and upper receivers are aluminum alloy with a hard-anodized black finish.
Ergonomics include a telescoping polymer stock and a black polymer pistol grip with a ROSE motif. SIG's Matchlite Duo 2-stage trigger is fitted from the factory. The rifle uses a semi-automatic, direct impingement action and has a 30+1 capacity.
An installed SIG SAUER ROMEO5X GEN II ROSE red-dot sight provides a clean, modern aiming solution. The rifle also includes an installed M-LOK hand stop, two 30-round PMAGs, and a SIG SAUER ROSE soft case with a detachable shoulder strap for transport.
