The SOG AR-15 piston-driven sporting rifle for the civilian market is a proven design based on the military M4 model. These Mil-spec rifles are fully compatible with parts from most AR-15 component manufacturers. The very high-quality finish, anodized coatings, and precise selection of parts ensure not only an aesthetic appearance but also durable and reliable operation of the rifle. The rifle, equipped with the SOG short-stroke piston system, offers greater reliability compared to standard direct impingement (DI) systems.
