About the Sig Sauer M400 Forge
This is the M400 Forge in its 10rd configuration, sold into states where magazine capacity is limited and bought elsewhere by shooters who simply prefer a shorter magazine off a bench. Everything else matches the standard rifle: a 16" cold hammer forged barrel with a mid length gas system, an A2 flash hider on 1/2-28 threads, and a Romeo-MSR Gen II red dot with a 2 MOA aiming point mounted at the factory.
Sig put a TriggerTech two stage flat blade duty trigger in this rifle, and it is the single largest upgrade over a standard fire control group. Take up is smooth, the wall is obvious, and the break is clean and repeatable. The handguard is a 15" free float M-LOK tube with a continuous top rail, leaving room for a light, a laser or a hand stop wherever the support hand lands. Controls include an ambidextrous charging handle, and the Magpul SL-K stock collapses through six positions for shooters in armor or heavy layers. Forged aluminum receivers wear a black anodized finish. Mid length gas timing gives the bolt carrier a longer, gentler push than a carbine port, which shows up as less felt recoil and a flatter sight picture between shots.
