Great Six8: Top 13 Firearms on the 6.8 Spectrum

Best of the SOCOM-born DGI and piston-driven ARs in 6.8 SPC built for today’s marksmen who demand more punch.

The 6.8 SPC was developed after the U.S. Special Operations Command (USSOCOM) shelved a program to create a modular, special-purpose rifle that could fire both 5.56mm NATO and 7.62x39mm ammo. During that program, USSOCOM discovered that the 7.62x39mm had slightly better terminal performance than the 5.56mm—exactly what many operators in Iraq and Afghanistan had also noticed.

The Enhanced Rifle Cartridge (ERC) program rolled out of the modular rifle program and was headed up by USSOCOM and aided by Remington. To develop the 6.8 SPC, a shortened .30 Remington case was used with a .270 bullet—the same bullet used in the .270 Winchester cartridge. This bullet has a good ballistic coefficient (BC) with less air resistance in flight, good accuracy and plenty of downrange energy.

More rifles and carbines currently made in 6.8 SPC have a Spec II chamber. By 2004, civilians had access to the 6.8 SPC, and the round has become a popular AR caliber for hog and deer hunters as well as those serious about personal and home defense. The Saudi government’s armed forces also use the 6.8 SPC. Since the round was designed to fit in the AR-15 platform, only a few internal components are different than the 5.56mm’s: the bolt head, magazine and barrel.

Accuracy and terminal ballistics matter. Here are some of the best 6.8 SPC rifles and carbines available on the market today.
