Great Lakes GL15 | .450 Bushmaster | 18in Nitride

The Great Lakes GL15 is an AR-style modern sporting rifle chambered in .450 Bushmaster with an 18-inch nitride-treated barrel and Tungsten Grey Cerakote finish. It ships with a single 5-round modified black Lancer magazine and a 15-inch M-LOK aluminum handguard for accessory flexibility. For optics under $1,000, the Vortex Strike Eagle 1-6×24 is a capable, value-priced optic that pairs well with this platform for short-range precision and quick acquisition.

The included 15″ M-LOK handguard and single modified Lancer magazine keep the package lean while the nitride barrel finish and Cerakote provide corrosion resistance for field use. Optic options like a 1-6x close- to mid-range scope or a low-power variable will maximize the cartridge’s useful range without overcomplicating the setup.
