Great Lakes GL10308SSBLK .308 Win Semi-Auto Rifle
About this product
The Great Lakes GL10308SSBLK is a .308 Winchester semi-automatic rifle built on 7075 aluminum billet receivers with a 20-inch stainless steel barrel featuring a 1:10 twist rate. With an overall length of 38.5 inches and weight of 8.25 pounds, this platform bridges the gap between precision accuracy and reliable semi-automatic function. The rifle-length gas system and M-LOK handguard make it ready for both suppressor use and accessory mounting right out of the box.
What is the GL10308SSBLK used for?
This rifle excels at medium-range precision shooting and hunting applications where .308's ballistics provide decisive terminal performance. The 20-inch barrel optimizes velocity for shots out to 600 yards while maintaining manageable handling compared to longer barreled bolt actions. I'd recommend it for deer hunting in mixed terrain or tactical competitions requiring rapid follow-up shots.
How does the GL10308SSBLK compare to the Stevens 334?
The GL10308SSBLK provides semi-automatic capability that the bolt-action Stevens 334 lacks, at the cost of approximately 2.5 pounds additional weight. While the Stevens 334 delivers sub-MOA accuracy potential for $200 less, the Great Lakes rifle offers faster target re-engagement and better accessory integration through its M-LOK system. For driven hunts or defensive scenarios, the semi-auto function justifies the premium.
What does it weigh and what are the dimensions?
This rifle weighs 8.25 pounds unloaded and measures 38.5 inches in overall length with the stock fully extended. The 15.25-inch handguard provides ample real estate for support hand placement and accessory mounting, while the 20-inch barrel maintains full powder burn for consistent velocities. At 5/8"-24 threaded muzzle, it accepts common .308 suppressors without adapter requirements.
Who is this NOT for?
Budget-conscious shooters seeking maximum accuracy per dollar should consider bolt actions like the Stevens 334 instead. The 8.25-pound weight makes it unsuitable for extended backpack hunts where every ounce matters. Those in restricted jurisdictions should verify local compliance regarding semiautomatic centerfire rifles before purchase.
What's in the box?
The rifle ships with one 10-round PMAG compatible magazine, though capacity may vary based on state regulations. You'll need to supply your own optic, sights, and sling - this is a barebones platform ready for customization. The package includes basic documentation but no tools or cleaning kit, consistent with most firearms in this price bracket.
Is the GL10308SSBLK worth it at $968?
At $968, this rifle occupies a competitive space between entry-level AR-10 platforms and custom builds. The billet construction and rifle-length gas system provide a solid foundation that cheaper DI guns often compromise on. For shooters wanting .308 semi-auto reliability without $1,500+ price tags, this represents solid value - though you'll still need to budget $300-800 for optics and mounting hardware.

Frequently asked questions
- Is it compatible with AR-10 pattern magazines?
- Yes, it accepts standard DPMS-pattern .308 magazines including Magpul PMAGs. The included magazine capacity varies by state but typically ships with a 10-round polymer magazine. Verify local restrictions before ordering higher-capacity replacements.
- Does it fit standard AR-15 accessories?
- The M-LOK handguard accepts most AR-15 accessories, but the larger .308 platform requires specific parts for the receiver and buffer system. Stocks and grips compatible with AR-10/DPMS patterns will fit, but the bolt carrier group and charging handle are platform-specific.
- How long does shipping take?
- Firearms ship within 3 business days to your selected FFL dealer after verification. Transit time varies by carrier but typically adds 2-5 business days. You must coordinate transfer paperwork directly with your FFL upon arrival.
- Can I return it if there are issues?
- Returns require manufacturer authorization within 30 days for defective items. Non-defective firearms generally cannot be returned due to federal regulations. Ironclad Armory provides lifetime warranty coverage on manufacturing defects through Great Lakes Firearms.
- Does this work with suppressor mounts?
- The 5/8"-24 threaded muzzle accepts most .30 caliber suppressors directly. For quick-detach systems, you'll need a compatible muzzle device like the SilencerCo ASR brake or Dead Air KeyMo adapter. Always verify thread alignment with a gauge before suppressor mounting.
