Great Lakes Firearms AR-15 .350 Legend 16" Tungsten/SS 5-Round Rifle

The Great Lakes Firearms AR-15 chambered in .350 Legend offers a lightweight, semi-automatic platform purpose-built for hunters and shooters who want modern rifle capability in a compact, manageable package. This 16-inch barreled rifle combines practical ergonomics with solid construction, making it a natural fit for hunters moving through brush, hunters in vehicles, or anyone seeking a modern sporting rifle that doesn't demand a full-length centerfire commitment. The .350 Legend round itself—a relatively new, straight-walled cartridge—has gained traction in states with straight-walled centerfire hunting regulations, and this Great Lakes build delivers the ammunition's potential without unnecessary bulk.

The rifle is built on a proven AR-15 platform with a 7075-T6 aluminum upper and lower for rigidity and weight savings. Your choice of barrel steel—either corrosion-resistant stainless or 4150 chrome-moly with nitride hardening—keeps the gun lean at 6.4 pounds and ready for field work. The 16-inch barrel wears a 1:10 twist optimized for the cartridge, threads for aftermarket muzzles (9/16x24 standard), and arrives with a muzzle brake installed. A 15.25-inch handguard with full Picatinny rail lets you add optics, lights, or other tactical gear as your mission demands.

Handling is pure AR-15 familiar: mil-spec trigger (5.5–6 lb pull), mil-spec polymer grip, and a carbine-length gas system with 0.750-inch gas block. The rifle ships optics-ready, with no factory sights, so you can mount the sight picture that matches your hunting style. One five-round magazine is included; the compact capacity keeps the platform compliant in many jurisdictions while remaining quick to reload in the field.

Frequently Asked Questions

Is this .350 Legend rifle legal for hunting in states with straight-walled cartridge requirements?

The .350 Legend is a straight-walled cartridge approved for deer hunting in multiple states that restrict hunting centerfire rifle use to straight-walled rounds. Always verify your state and local hunting regulations before purchase and use, as laws vary by region.

What kind of optics can I mount on this rifle?

The 15.25-inch handguard is topped with a full Picatinny rail, so you can mount any standard Picatinny-compatible optic—scopes, red-dots, magnified combos, or backup iron sights. No factory sights come installed, giving you the freedom to set up your sight picture exactly how you want it.

Does this rifle come with magazines, and what's the capacity?

One five-round magazine is included with your rifle. The five-round capacity keeps the platform compliant with capacity restrictions in some areas while remaining practical for hunting and sport shooting.

Can I swap barrels or customize the muzzle brake?

The muzzle brake is included and installed. The threads are 9/16x24, a common standard that accepts many aftermarket suppressors and brakes. Barrel swaps are possible on the AR-15 platform, but any modifications should be performed by someone familiar with firearms assembly and local law.
