The Sig Sauer M400 Forge 5.56 NATO SBR with Romeo-MSR Gen II Red Dot pairs a proven AR-platform short-barreled rifle with a factory-mounted optic for fast, confident shooting. Its 11.5" cold hammer forged barrel, aluminum handguard, and ambidextrous charging handle deliver a balanced, durable setup that stays controllable and consistent shot after shot. A TriggerTech 3.5 lb two-stage flat blade duty trigger provides a clean, predictable break for precise fire.

This compact M400 Forge SBR is well suited for home protection, training, and range use where a shorter overall length and quick handling are priorities. The included Romeo-MSR Gen II 2 MOA red dot offers a clear aiming point for rapid target transitions, while the adjustable stock helps different shooters find a comfortable fit. Backed by Sig Sauer’s long-standing reputation for accuracy and reliability, this rifle arrives ready for serious use right out of the box.
