Great Lakes Firearms and Ammunition AR-15 Features The Great Lakes Firearms and Ammunition AR-15 runs a black nitride finished barrel chambered in .350 Legend cut with a 1:16 twist rate that stabilizes the heavier bullets common to this straight-walled hunting cartridge for consistent downrange accuracy. The low-profile gas block keeps the sight lines clean while regulating the semi-automatic gas system for reliable cycling. Forged 7075-T6 aluminum upper and lower receivers provide a durable lightweight foundation and the flat-top upper carries a full-length Picatinny rail so shooters can mount their optic of choice directly out of the box. Mil-spec controls keep the manual of arms familiar to any AR-platform shooter. Finished in Bronze Cerakote over the receivers with a black stock and handguard the Great Lakes Firearms and Ammunition AR-15 stands out from a typical black rifle while retaining Cerakote s corrosion resistance. The 15 free-float M-LOK compatible handguard gives shooters room to mount lights foregrips and bipods without contacting the barrel and the 6-position collapsible stock allows quick length-of-pull adjustment for different shooters or shooting positions. Ships complete with one 5-round magazine ready to hunt or shoot straight from the box.
