Sig Sauer M400 Forge SBR 5.56 NATO 30rd, Black + Romeo-MSR
2 in stock
Description
The Sig Sauer M400 Forge SBR is a factory short-barreled rifle built on Sig's duty-grade AR-15 platform, chambered in 5.56 NATO and paired with a Romeo-MSR Gen II red dot straight from the box. An 11.5-inch cold hammer forged barrel running a carbine-length gas system keeps the package short without giving up the reliability expected of a service-pattern direct impingement rifle.
Shooters looking for a compact 5.56 for home defense, truck duty, or training in tight spaces will find the configuration well sorted. The TriggerTech two-stage flat blade trigger, ambidextrous controls, and free-floating M-LOK handguard cover the upgrades most buyers would otherwise add later, and the included 2 MOA optic means the rifle is ready to zero on arrival.
