The Great Lakes Firearms GL10308SSTNG GLFA .308 Win 10+1 18″ Cerakote Threaded Barrel, Tungsten Cerakote Picatinny Rail Aluminum Receiver, 6 Position Mil-Spec Synthetic Stock, Mil-Spec Polymer Grip is a ready-to-shoot large-frame AR platform built for families who want a reliable .308 without the custom-build hassle. This rifle ships with a 15.125″ M-LOK rail, rifle-length gas system, and a crisp mil-spec trigger—all finished in a durable Tungsten Cerakote.

Key Features

• 18″ Threaded Barrel with 5/8″x24 Threads – WHY IT MATTERS: This profile balances maneuverability with .308 velocity, and the common thread pitch lets you easily add a suppressor or muzzle brake for quieter family-range sessions.
• 15.125″ M-LOK Free-Float Rail – WHY IT MATTERS: The full-length rail keeps your support hand secure and lets you mount lights, bipods, or grips exactly where your shooter needs them—no wobble, no shift.
• Aluminum Billet Upper and Lower Receiver – WHY IT MATTERS: Billet construction means tighter tolerances than forged receivers, giving you a more consistent lockup and better accuracy potential right out of the box.
• Rifle-Length Gas System – WHY IT MATTERS: A longer gas system reduces bolt carrier speed and felt recoil, which is a real plus when teaching new shooters or running heavy .308 loads.
• 6-Position Mil-Spec Collapsible Stock – WHY IT MATTERS: Adjust length of pull to fit different-sized family members—from a teen’s first deer hunt to an adult’s prone position—without tools.

Who It’s For

This GLFA .308 is for the family that wants one rifle for target practice, deer season, and home defense training. It’s also ideal for the first-time large-frame AR buyer who wants a complete, factory-assembled gun with a threaded barrel and M-LOK rail—no building, no guessing.

Pros / Cons

• PRO: Tungsten Cerakote finish resists rust and scratches from range bags and truck beds.
• PRO: Includes a 10-round magazine—compliant in most states right away.
• CON: The mil-spec trigger is functional but heavier than aftermarket options; many shooters upgrade later to a Geissele or Timney for precision work.

How It Stacks Up

Compared to the Zev OZ-9 (a 9mm pistol) and the Agency Arms .308, the GLFA offers a complete, ready-to-shoot .308 at roughly half the price of a custom build. It’s not as refined as an Agency Arms, but it’s far more accessible for a family’s first large-frame AR.
