Key Features
- 400 Legend Chambering – This cartridge delivers a 35-caliber bullet at 2,200+ fps with significantly less recoil than a .450 Bushmaster or .308 Win. That means your kids or spouse can shoot it comfortably and accurately.
- Bronze Cerakote Finish – The durable ceramic coating resists rust, scratches, and wear from field use. It also gives the rifle a distinct, low-glare appearance that won’t spook game.
- 16.50-Inch Stainless Barrel – The threaded barrel (5/8×24) accepts standard muzzle devices or suppressors. Stainless steel provides excellent corrosion resistance and consistent accuracy.
- M-LOK Handguard – Lightweight and modular, the M-LOK handguard lets you attach a bipod, foregrip, or light without adding bulky rails. It also keeps your hand cool during rapid fire.
- Billet Aluminum Receiver – Machined from a solid block of 7075-T6 aluminum, the upper and lower receiver are stronger and more precise than forged alternatives. This ensures a tight fit for optics and accessories.
Who It’s For
This rifle is built for families who hunt whitetail or black bear in states where straight-wall cartridges are required (like Ohio, Indiana, Michigan, and Pennsylvania). It’s also a great choice for new shooters who want a low-recoil AR that’s easy to clean and maintain. The 400 Legend’s flat trajectory makes it forgiving for beginners.
Pros / Cons
- Pros: Low recoil, excellent accuracy out to 200 yards, durable Cerakote finish, modular M-LOK handguard, threaded barrel, and lightweight billet receiver.
- Cons: The polymer trigger feels a bit heavy (around 6.5 lbs) compared to aftermarket triggers. Swapping it for a Timney or Geissele drop-in is an easy upgrade.

FAQ
What is the barrel twist rate?
The 16.50-inch stainless barrel has a 1:16 twist rate, optimized for the 400 Legend’s 180-200 grain bullets. This stabilizes factory loads well for hunting accuracy.
Does it come with a magazine?
Yes, the GL15 includes one 5-round magazine. It also accepts standard AR-15 magazines chambered for 400 Legend.
Can I mount a scope directly to the Picatinny rail?
Yes. The aluminum upper receiver has a full-length Picatinny rail (1913 spec) that accepts rings or one-piece mounts for scopes, red dots, or holographic sights.
Is this rifle legal in states with straight-wall cartridge laws?
Yes. The 400 Legend is a straight-wall cartridge specifically designed to meet regulations in Ohio, Indiana, Michigan, Pennsylvania, and other states that restrict rifle cartridges for deer hunting.
How do I clean the bronze Cerakote finish?
Use a soft cloth with mild soap and water. Avoid abrasive cleaners or steel wool. Cerakote is durable but can be scratched by harsh chemicals.
