The Great Lakes Firearms AR-10 in 7mm Rem Mag brings serious long-range punch in a platform you already know how to run. If you're accustomed to the AR-15 ergonomics and controls, this stainless steel AR-10 chamber in 7mm delivers the extended range and terminal performance that separate ethical long-distance hunting from wishful thinking. The GL10LA (long-action) design leverages AR-10 compatibility while stepping up to a cartridge built for elk, deer, and other game at distances where smaller calibers leave too much to chance.
Build quality starts with a 24-inch barrel of 416R stainless steel, treated with 5R rifling and a 1:10 twist optimized for 7mm ballistics. The muzzle brake (5/8 x 24) helps manage recoil—a real consideration when you're shooting a magnum in a rifle that tips the scales at just over 9 pounds. The lower is 7075 aluminum billet, upper is billet aluminum, and the gas system runs rifle-length, all contributing to reliable feeding and cycling with that custom-design bolt carrier group. The 20-inch M-Lok handguard provides mounting real estate for optics, lights, or other accessories without unnecessary bulk.
The fixed Hogue stock in black keeps things simple and proven. Trigger breaks at 5.5 to 6 pounds—standard mil-spec, predictable, and suitable for hunting or precision work. Feeding is handled by Great Lakes' custom 5-round aluminum magazine, and the rifle ships ready to pair with optics on the upper receiver rail. At 45.50 inches overall and 9.25 pounds empty, this is a rifle that handles like an AR but demands respect for what it can do downrange.
If your hunting grounds stretch beyond 300 yards and you want the accuracy and reliability of an AR platform without compromise, the 7mm Rem Mag GL10LA earns its place in the truck bed.

The 7mm Rem Mag is a legitimate long-range cartridge, and the 24-inch stainless barrel with optimized 1:10 twist is designed to take advantage of that performance. Effective range depends on your optics, ammunition, and skill, but this caliber and barrel combo are built for distance. We can't make promises beyond what ammunition and your shooting ability allow.
