The Great Lakes Firearms AR-15 in 400 Legend with a 16-inch barrel is a modern sporting rifle built on a proven platform and chambered for an intermediate cartridge that splits the difference between common pistol and rifle rounds. This particular model features a pursuit green Cerakote finish on a 7075 billet lower receiver paired with a 416R stainless steel barrel, giving you a rifle that's both durable and visually distinctive. Whether you're looking to explore a new cartridge or want a versatile AR-15 that stands out on the range or in the field, this Great Lakes Firearms rifle delivers solid construction without unnecessary complexity.
The 16-inch barrel with a 1:16 twist rate is threaded 5/8x24, giving you options for muzzle devices down the road. The upper receiver rides on a 15.125-inch M-LOK handguard, which provides ample real estate for mounting optics, lights, or other accessories without weighing you down. A 5-round magazine comes with the rifle, keeping things simple and straightforward.
Great Lakes Firearms has a solid reputation in the AR community for attention to detail and no-nonsense builds. The 400 Legend cartridge has gained a following among shooters who want something between a pistol round and a full rifle cartridge—it's worth researching if you're new to the round. This rifle gives you a quality platform to explore it.

The 400 Legend is an intermediate cartridge designed for the AR platform. Because it's chambered in an AR-15, most standard AR accessories—rail-mounted optics, lights, and grips—will work with this rifle. However, ammunition and magazines specific to 400 Legend must be matched to the cartridge; it is not compatible with 5.56 NATO or .300 Blackout.
Yes. The barrel is threaded 5/8x24, which is a common threading pitch. You can attach a suppressor, flash hider, muzzle brake, or other compatible device to the muzzle.
