The M400 ROSE series is part of SIG’s ROSE program led with Lena Miculek. This factory edition stands out with ROSE script engraving on the free-floating M-LOK handguard and coordinated rose-gold/copper-tone controls and muzzle device over a black anodized finish. The receiver is aluminum alloy and marked SIG SAUER INC, NEWINGTON NH, USA.
It uses a rotating-bolt, direct-impingement operating system with a 16-inch threaded barrel. A 1913 Picatinny rail on the upper receiver provides mounting for optics, while the free-float handguard is a slick-top M-LOK design (no 12 o'clock Picatinny rail) and includes an integrated low-profile hand stop and an M-LOK QD sling socket. The rifle accepts AR-15/STANAG pattern magazines.
Controls and ergonomics include an ambidextrous safety selector and a flat-faced trigger. Furniture consists of a Magpul MOE SL adjustable stock and a SIG polymer pistol grip with the ROSE logo, all in a black finish.
This example arrives range-ready with the SIG Sauer ROMEO5X ROSE red-dot sight installed, two 30-round PMAG GEN M3 magazines, and both a SIG ROSE soft rifle case and the original case. A webbing sling with snap-hook attachments is also included.
