Description
There are plenty of AR-10 pattern rifles out there, but not many show up with a finish like this. Great Lakes Firearms applies their Cerakote in house, and the burnt bronze on this GL10 makes it look like a custom build instead of a rack gun. Underneath the good looks is a rifle built in Michigan with billet 7075 aluminum upper and lower receivers, a 15 inch free float M-LOK handguard, and a full length top rail ready for whatever glass you want to run.
The Barrel Does the Heavy Lifting on This GL10
The 18 inch 416R stainless steel barrel is where this rifle earns its keep. It features 5R rifling with a 1:10 twist, and each barrel is double thermally stress relieved and air gauged, which is the kind of attention you usually see on barrels costing quite a bit more. The muzzle is threaded 5/8×24 and wears a ported brake from the factory, which takes real bite out of .308 recoil and keeps you on target for follow-up shots. A rifle-length gas system smooths out the cycling, so this big-bore AR is more pleasant to spend a full day behind than you might expect.
A .308 That Pulls Double Duty in the Field and at the Range
With .308 Winchester on tap, this rifle covers a lot of ground. It has the punch for whitetail, elk, hogs, and black bear, and the accuracy for steel, silhouette, and stretching things out past 500 yards on paper. The 6 position adjustable stock lets you set length of pull for heavy jackets or bench work, and at around 8.25 pounds it balances well for a rifle in this class.
Why the Great Lakes GL10308SSBRZ Is Worth a Look
It ships with one 10 round magazine and arrives optics ready with no sights installed, so plan on adding a scope or red dot. For anyone wanting a .308 AR that shoots straight, soaks up recoil, and stands out on the rack, this one delivers well beyond what the price tag suggests.

Frequently Asked Questions
Does the Great Lakes GL10308SSBRZ come with sights?
No, this rifle ships optics ready with no iron sights installed. The full-length Picatinny top rail on the receiver and handguard gives you plenty of room to mount a scope, LPVO, or red dot. Most buyers pair a .308 like this with magnified glass to take advantage of the cartridge's reach.
What magazines does this Great Lakes AR-10 use?
It ships with one 10-round magazine and runs on standard SR-25/DPMS pattern .308 magazines, which are the most common type on the market. That means Magpul PMAG 25 LR/SR mags and similar options will work if you want more capacity or spares.
Is the GL10 in .308 a good hunting rifle?
It is a strong choice for big game. The .308 Winchester has more than enough energy for whitetail, hogs, elk, and black bear at practical hunting distances, and the 18 inch stainless barrel with 5R rifling delivers the accuracy for clean, ethical shots. The factory muzzle brake also tames recoil noticeably, which helps with quick follow-ups.
Can I run a suppressor on the GL10308SSBRZ?
Yes. The barrel is threaded 5/8×24, which is the standard thread pitch for .30 caliber suppressors and muzzle devices. Just remove the factory brake and you can install a direct-thread can or a suppressor mount of your choice.
