The Great Lakes GL10 in .300 Winchester Magnum (MPN GL10LA300SSBLK) is a large-frame AR-platform rifle built around a billet upper and lower receiver and a 24-inch stainless steel barrel rifled at a 1:10-inch twist for long-range magnum performance. Great Lakes finishes the barrel in Cerakote black, adds a 20-inch aluminum M-LOK handguard, a custom bolt carrier group, and a 5/8×24 stainless muzzle brake, then tops it off with a Hogue fixed rifle stock for a stable long-range platform. The rifle feeds from a detachable 5-round magazine and uses a thumb safety. Among AR-pattern rifles in the AR rifles category, the GL10 favors long-range hunters who want magnum power in a modern AR-10-style platform.
