The Great Lakes AR-15 .350 Legend Black/Stainless rifle is a semi-automatic .350 Legend from Great Lakes Firearms and Ammunition (brand part no. GL15350SSBLK16), shown here in the Black/Stainless colorway. It pairs a 16-inch barrel with a 1:10 twist and a 7075 aluminum upper with a 15.25-inch aluminum handguard carrying a full Picatinny rail. The muzzle is threaded 9/16×24 and an included muzzle brake sits on it, while a mil-spec trigger breaks at 5.5 to 6 pounds. It feeds from a 5-round magazine, one of which is included, and it ships with no sights installed so the optic is your choice. At 33.25 inches overall and about 6.4 pounds, it is a compact semi-auto for hunters working thick cover.
