The Great Lakes Firearms 400 Legend is a modern sporting rifle built for hunters and shooters who want a versatile, hard-hitting platform in an efficient package. This 16-inch rifle pairs a 416R stainless steel barrel with a 7075 billet lower receiver finished in distinctive OD Green Cerakote, delivering a rugged, field-ready aesthetic without sacrificing durability. The 400 Legend chambering offers hunters a flat-shooting, low-recoil alternative to traditional rifle cartridges, making it an excellent choice for medium-range hunting and target shooting where accuracy and reliability matter.
The 16-inch barrel is configured with a 1:16 twist rate and 5/8x24 thread pitch, allowing you to add a suppressor or muzzle brake if your setup demands it. The rifle ships with a single 5-round magazine, providing a compact, legal-compliant configuration suitable for most hunting regulations. Up top, the 15.125-inch M-Lok handguard gives you plenty of mounting real estate for lights, lasers, or other tactical accessories without unnecessary bulk.
Great Lakes Firearms built this rifle for shooters who understand that a quality lower receiver and premium barrel steel translate to real performance. The 7075 billet construction and stainless barrel ensure this rifle will handle years of field use, and the OD Green finish blends function with modern aesthetics. Whether you're pursuing game at moderate distances or running drills at the range, the 400 Legend platform delivers the accuracy and reliability you expect from a purpose-built rifle.
