Build Quality and Design

One of the strongest aspects of the M400 series is its impressive construction quality. SIG Sauer machines both the upper and lower receivers from aircraft-grade aluminum, providing durability without adding unnecessary weight.

Performance and Reliability Tested

Performance is where the M400 truly stands out.

During extended range sessions, the rifle cycles smoothly with a wide range of factory ammunition. The mid-length gas system helps reduce felt recoil while improving overall shooting comfort compared to many carbine-length systems.
