The SIGM400 is a family of firearms manufactured by SIG Sauer.[1] The M400 is an air-cooled, direct impingement gas-operated, magazine-fed carbine that is based on the earlier AR-15 rifle.[2] Depending on the variant, it can be chambered for 5.56×45mm NATO or .300 AAC Blackout cartridges, and may have a fixed or telescoping stock.[3]
Design details
[edit]Operating mechanism
[edit]The SIGM400 is a semi-automatic firearm in either rifle as the SIGM400 Classic, SRP, Tread, Elite, Predator or pistol as the Elite PSB, intended for law enforcement, military and civilian markets. It fires from a closed bolt and uses a direct impingement gas system.[3]
Features
[edit]The SIGM400 Predator is a rifle while the SIGPM400 Elite PSB is a pistol. The rifles are chambered for either 5.56×45mm NATO with 14.5-inch (37 cm), 16-inch (41 cm), 18-inch (46 cm), or 20-inch (51 cm) barrels threaded 1/2x28, or chambered for .300 AAC Blackout with 9-inch (23 cm) or 16-inch (41 cm) barrels which are threaded 5/8x24 for muzzle devices such as sound suppressors. There are California compliant ("featureless") models for both.[3] The .300 AAC Blackout model is tailored specifically for efficient use with suppressors. The Picatinny rail supports optical, electro optical, or iron sights. SIG Sauer also manufactures suitable suppressors.
The SIGPM400 Elite PSB pistol is chambered for 5.56×45mm NATO with an 11.5-inch (29 cm) barrel and is chambered for .300 AAC Blackout with a 9-inch (23 cm) barrel. Both use a Pistol Stabilizing Brace accessory.[3]
