The Great Lakes GL-15 400 Legend 16in SS Barrel OD Green 5rd is a field-ready modern sporting rifle built for hunters and target shooters who want straight-wall performance in an AR platform. Chambered in .400 Legend, this semi-automatic rifle combines a 16-inch stainless steel barrel with a 1:16 twist, a threaded muzzle, and a durable OD Green Cerakote finish. It ships with a 15-inch M-LOK handguard, an adjustable synthetic stock, mil-spec controls, and a 5-round detachable magazine. Per Great Lakes specs, the billet aluminum upper and lower receivers keep weight low and accuracy high.

Key Features
- 16-inch stainless barrel with 1:16 twist — why it matters: the stainless steel barrel resists corrosion in wet field conditions, and the 1:16 twist stabilizes .400 Legend bullets from 180 to 250 grains for consistent accuracy at deer-hunting ranges.
- OD Green Cerakote finish — why it matters: this baked-on coating protects against scratches, rust, and harsh weather, keeping the rifle looking sharp through seasons of use.
- Billet aluminum upper and lower receivers — why it matters: machined from solid blocks, these receivers offer tighter tolerances than forged parts, improving fit and reducing slop between components.
- 15-inch M-LOK handguard — why it matters: the free-float design keeps barrel harmonics consistent for better accuracy, and the M-LOK slots let you mount lights, bipods, or slings exactly where you need them.
- Adjustable synthetic stock and mil-spec controls — why it matters: the stock adjusts for length of pull to fit smaller or larger shooters, and the mil-spec safety, bolt catch, and magazine release are familiar to anyone who’s used an AR-15.
Who It’s For
This rifle is built for hunters in states that require straight-wall cartridges for deer season, like Ohio, Michigan, Indiana, and Iowa. It also suits target shooters who want a flat-shooting round with less recoil than .450 Bushmaster or .350 Legend. Family shooters will appreciate the 5-round magazine for range trips with newer shooters, and the adjustable stock makes it easy to share the rifle among different-sized family members.
Pros and Cons
- Pros: Straight-wall legality for deer hunting, stainless barrel for corrosion resistance, billet receivers for tight fit, M-LOK handguard for accessory mounting, adjustable stock for family use.
- Cons: Limited to 5-round magazine (may not suit shooters who want higher capacity for competition or plinking).

FAQ
What is the effective range of the .400 Legend?
The .400 Legend is effective for deer hunting out to about 250 yards with proper bullet selection. Its straight-wall design keeps it legal in states that restrict rifle cartridges, but it drops more at longer ranges than .223 Wylde or 6.5 Grendel.
Can I use standard AR-15 magazines with this rifle?
No. The .400 Legend requires specific magazines designed for the cartridge. The GL-15 ships with a 5-round detachable magazine that is proprietary to the .400 Legend platform. Standard 5.56 NATO or .223 Remington magazines will not fit or function.
Is the muzzle threaded for a suppressor or brake?
Yes, the 16-inch stainless barrel has a threaded muzzle (5/8×24), so you can attach a muzzle brake, compensator, or suppressor. Just check local laws before adding a can.
Does this rifle come with iron sights?
No, the GL-15 does not include iron sights. The M-LOK handguard and Picatinny rail on the upper receiver allow you to mount your choice of optics, red dots, or flip-up sights.
