Description
Product Overview
The CMMG M4 LE K3B is a duty-oriented AR-15 rifle chambered in 5.56 NATO and capable of accepting .223 Remington ammunition. Its 16-inch M4-profile barrel is made from 4140 chrome-moly steel and receives CMMG’s WASP treatment for added surface protection. A six-position collapsible stock supports adaptable handling, while the M4 handguard preserves the familiar carbine configuration.
