In their product walkthrough on Greyhive, SIG SAUER frames the M400-FORGE as the rifle for shooters who \"demand more\" out of a baseline AR — a 16-inch carbine that ships ready to run out of the box, with the forged receivers, M-LOK handguard, and 30-round magazine compatibility most buyers expect in 2026.
