Great Lakes GL-10

GL-10 vs. GL-15 — Choosing Your Platform

The GL-15 is GLFA's AR-15 in 5.56 NATO — lighter, higher capacity, and the practical choice for most applications. The GL-10 steps up to the AR-10 pattern in .308 Win — more power, more energy at distance, and the ability to take larger game cleanly at ranges where 5.56 is marginal. Choose the GL-15 for general use, competition, and varmint hunting. Choose the GL-10 when you need .308 Win terminal performance — deer, hogs, elk, and extended-range precision shooting.

Key Features

Forged 7075-T6 receivers — The same aluminum alloy and forging process as the GL-15. AR-10 pattern receivers scaled for the demands of the .308 cartridge — higher bolt thrust, heavier bolt carrier group, and greater overall operating forces than the smaller AR-15 pattern.

Cold-hammer-forged barrel — GLFA's CHF barrel in .308 Win, producing the hardness and bore consistency that make CHF barrels the standard for accuracy and longevity in serious rifle applications.

DPMS pattern lower — The GL-10 uses a DPMS-compatible lower receiver, accepting DPMS-pattern .308 AR magazines and compatible with the broad range of DPMS-footprint stocks, grips, and accessories. Note: DPMS-pattern and Armalite-pattern AR-10 components are not interchangeable — verify compatibility before purchasing accessories.

Who the GL-10 Is For

The GL-10 is the practical choice for hunters who want a .308 Win AR for deer, hogs, or elk; precision shooters who want .308 capability at extended ranges; and buyers who specifically want American-made AR-10 quality without the premium pricing of BCM, Daniel Defense, or LWRC's .308 offerings.
