ARMALITE M-15A4 6.8 SPC
Reliable, fight-stopping power in a compact carbine!
Aficionados of “traditional” firearms like old name brands. An AR-15 buyer has an array of more than 70 companies to choose from when they want to add a rifle of this time-tested platform to their collection. There’s a certain mystique to buying a Colt AR-15. But if you want to buy a rifle from the original company that gave the AR its namesake, ArmaLite, Inc., then purchasing an M-15 makes perfect sense.

Professionals who want enhanced stopping power from their duty rifle will be well served with Armalite’s M-15A4 chambered in 6.8 SPC. Shown here with the Trijicon 4x ACOG.
If you are ready to add a 6.8 SPC-chambered AR-platform rifle to your collection, then ArmaLite’s addition of this caliber to its lineup is good news. On the other hand, you may be a law enforcement officer who has learned that a .22-caliber rifle is a good weapon, but it has its limitations. The special operations community has its reasons for upgrading to a larger-caliber rifle. The LE community also has learned the hard way that defeating barriers reliably, such as auto windshield glass, potentially requires more energy and bullet mass than provided by a 5.56mm NATO cartridge. Answering that call, too, ArmaLite’s M-15A4 Carbine chambered in 6.8 SPC is a good alternative when shopping for a duty carbine.

The M-15A4 employs a mid-length gas system that offers cleaner and potentially more reliable operation than a carbine-length gas system.
Built on the same platform as the ArmaLite M-15A4 Carbine, the company started shipping their first rifles in 6.8 SPC only recently. To get the highest performance possible from this cartridge, ArmaLite has chosen to chamber their rifles in the Spec II configuration.

The mil-spec bolt carrier is made from Carpenter 158 steel and features a gas key that works with the direct gas impingement system.
