The Great Lakes Firearms AR-15 is a semi-automatic rifle chambered in .223 Wylde with a 16-inch nitride-finished barrel and a 1:8 twist. It ships with a carbine gas system, M4 feed ramps, and a 15.25-inch aluminum M-LOK handguard under an OD Green cerakote finish. The .223 Wylde chamber lets it run both .223 Remington and 5.56 NATO ammunition.

Great Lakes Firearms builds get generally positive feedback for running reliably out of the box, especially given the price point. The nitride barrel finish holds up well against corrosion, and the .223 Wylde chamber is popular with owners who want to shoot both .223 Remington and 5.56 NATO without picking one or the other. A minority of buyers report checking or staking the gas block after the first range trip, which is common advice for budget-friendly AR-15 builds generally.

The 15.25-inch M-LOK handguard is a common favorite, since it gives plenty of real estate for a light, sling mount, or foregrip without needing rail adapters. The OD Green cerakote finish gets compliments for standing out next to a plain black rifle at a similar price, and recoil off the carbine gas system is mild and easy to manage for range days and plinking.

Because it is built on a standard AR-15 platform, parts and accessories are widely available, and swapping furniture, optics, or triggers is straightforward. Buyers generally see this rifle as good value for a threaded, optics-ready AR-15, though some choose to upgrade the factory trigger for a lighter aftermarket unit.
