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.

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.



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.



The M-15A4 employs a mid-length gas system that offers cleaner and potentially more reliable operation than a carbine-length gas system.



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