Sig Sauer
The Sig Sauer M400 ROSE 5.56 NATO rifle is purpose-built for shooters seeking a modern AR platform with thoughtful ergonomics and quality componentry. Developed in collaboration with competitive shooter and instructor Lena Miculek, the M400 ROSE combines the proven M400 platform with hand-picked features designed to deliver a shooter-centric experience. The 16-inch chrome-moly steel barrel with 1:7 twist rate cycles the popular 5.56 NATO cartridge with reliable mid-length direct impingement operation, while the semi-auto action delivers consistent performance whether you're training at the range or building marksmanship fundamentals.
Ergonomics are front and center here. The rifle ships with an ambidextrous manual safety and mag release, accommodating both left and right-handed shooters without modification. The 6-position Magpul MOE-SL stock is adjustable to fit different body frames and shooting styles, and the reduced-angle grip pairs with the SIG 2-Stage Matchlite Duo trigger—flat-faced for a direct, clean press. The 10-inch M-LOK handguard is free-floating for accuracy consistency and offers plenty of rail real estate for mounting lights, lasers, or other accessories without adding unnecessary bulk.
The ROMEO5 GENII red dot sight comes pre-installed and zeroed, letting you get rounds downrange immediately. Two 10-round polymer magazines are included, keeping you supplied for range sessions or training. At 7 pounds unloaded and 36.5 inches overall length (33.25 inches collapsed), the M400 ROSE stays light and maneuverable. The matte black receiver and rose gold-colored controls give the rifle a distinctive look while the SIG Flash Hider-Compensator manages recoil and blast signature. Everything from the trigger to the stock reflects real-world feedback from shooters of all skill levels, making this a straightforward, capable rifle for those stepping into the AR platform or adding to an existing collection.
