About the MK114 MOD 2-M 223

This complete upper receiver features a 223 Wylde chamber, which allows for reliable and accurate firing of both 5.56x45mm NATO and .223 Remington ammunition. The MOD 2-M designation indicates specific design enhancements, often including a free-float handguard and a refined gas system, contributing to consistent performance and improved handling.

As a complete upper, it is ready to attach to a standard AR-15 lower receiver. This makes it a suitable option for building a new rifle or upgrading an existing one for range shooting, varmint hunting, or general recreational use. Its 14.5-inch barrel length, when permanently affixed with a muzzle device to meet legal requirements, offers a balance of maneuverability and ballistic performance.
