Sig Sauer M400 ROSE 5.56 NATO 16" 10+1 Semi-Auto Rifle

The Sig Sauer M400 ROSE is a semi-automatic modern sporting rifle chambered in 5.56 NATO (and fully compatible with .223 Remington), built around a lightweight aluminum receiver finished in anodized black with the series' signature Rose Gold accent detailing. The ROSE variant blends familiar AR-pattern ergonomics with Sig Sauer's well-regarded fit, finish, and quality control, giving shooters a versatile carbine suitable for the range, training, home defense, or general field use.

Up front, a 16" threaded barrel with a 1:7" twist stabilizes the full spectrum of common .223/5.56 bullet weights, from lightweight varmint projectiles through heavier 77-grain open-pattern match and tactical loads. The barrel is paired with a mid-length direct-impingement gas system for smooth cycling and reduced felt recoil, and is capped with a Sig Sauer hybrid compensator/flash hider that tames muzzle rise and signature. The rifle ships with two 10-round magazines for an out-of-the-box 10+1 capacity.

The fire control group features a crisp 2-Stage Matchlite Duo trigger for a clean, predictable break, paired with an ambidextrous safety selector and ambidextrous-friendly controls that make the carbine equally comfortable for right- or left-handed shooters. The receiver is optics-ready via a standard top rail; no iron sights are included, allowing the end user to mount their preferred red dot, low-power variable, or magnifier setup.

Up top, a Magpul SL Telescoping buttstock lets shooters adjust the overall length from 33.25" to 36.50" to fit a wide variety of body types and shooting positions, including body armor and proper cheek weld behind an optic. The lightweight 7 lb carbine configuration keeps the M400 ROSE easy to carry on long range days or around the property.

Whether you are building out a home-defense lineup, picking up a flat-shooting varmint rifle, or looking for a dependable training carbine with the Sig Sauer name on the receiver, the M400 ROSE delivers modern AR-pattern performance with a distinctly premium touch.
