The Daniel Defense MK18 RIII URG is a complete upper receiver group with a 10.3 inch barrel in 5.56mm, finished in FDE. The MK18 configuration is a short-barrel carbine design long associated with close-quarters use, and Daniel Defense is known for its high-quality components.

The upper pairs a rail-mounted handguard with Daniel Defense's reputation for tight tolerances, offering a quick way to build or upgrade a short-barreled rifle or pistol. Because of its 10.3 inch barrel, make sure it is installed on a lawfully configured host, and check applicable regulations before purchase.
