The Great Lakes Firearms GL10308SSBLK AR-10 in 308 Winchester is a precision rifle built on a 20+1 capacity platform with an 18-inch stainless steel barrel and black receiver. This carbine-length configuration delivers a balanced profile suitable for intermediate-distance engagements while maintaining a practical overall length of 42 inches. The barrel features proprietary 5R rifling, double thermal stress-relief, and air-gauge verification—manufacturing processes that ensure consistent accuracy and repeatability across shot strings without point-of-impact shift.
The 18-inch heavy barrel incorporates rifle-length gas tube dynamics with a 0.750-inch gas block, optimizing dwell time and reducing carrier velocity spikes that accelerate component wear. Threading at 5/8"-24 accepts standard .308 muzzle devices; this rifle ships with a ported compensator hand-tightened to factory specification. The 15.25-inch aluminum M-Lok handguard provides modular accessory mounting and features a disrupted Picatinny rail on top for optics mounting and C-clamp attachment points. A standard A2 pistol grip and carbine stock round out the ergonomic package at 9.55 pounds—manageable for sustained shooting sessions without excessive fatigue.
This configuration suits marksmen and tactical shooters who require a 308 AR-10 for field training, precision rifle matches, or duty applications where the 308 Winchester's ballistic performance and magazine-fed platform combine effective range with operational simplicity. The stainless barrel resists corrosion in humid or coastal environments, while the black receiver contrasts cleanly against optics for target acquisition. Operators familiar with AR ergonomics transition seamlessly to this platform without retraining on manipulation or controls.
AR-10 rifles occupy the precision rifle segment between patrol carbines and bolt-action systems, offering semi-automatic rate of fire with inherent accuracy advantages over shorter-action platforms. The 308 cartridge delivers superior energy retention beyond 500 yards compared to 5.56 NATO, making it the standard choice for long-range work and hard-target applications where intermediate or defensive rifle performance is insufficient.
