The Daniel Defense MK18 Upper Receiver Group is a choice for those who demand reliability and performance. This upper receiver group features the same railed fore-end that Daniel Defense supplies to USSOCOM, ensuring it meets rigorous military standards.
At its heart lies a 10.3-inch Cold Hammer Forged Barrel, precisely designed for Close Quarters Battle (CQB) operations. The barrel length has been specifically chosen to offer optimal maneuverability without sacrificing effectiveness in confined environments.
The MK18 Rail Interface System II incorporates the renowned Bolt-Up System, tested extensively before being fielded by elite forces. It provides stability and versatility under demanding conditions.
An innovative feature of this setup is the independently ambidextrous GRIP-N-RIP Charging Handle. Engineered with left- and right-handed shooters in mind, it includes anti-gas properties that direct gas flow upward and away from the operator's face when firing suppressed—enhancing comfort during extended use.
Every complete upper receiver group from Daniel Defense comes standard with an M16 profile bolt carrier group, known for its durability and consistency under fire.
