Daniel Defense DD4 MK18 RIII 5.56mm NATO 10.3" Short Barrel Rifle 32RD

Daniel Defense’s MK18 RIII is an upgraded version of the popular MK18 platform, offering less weight and greater flexibility. This short barreled rifle is outfitted with the exclusive RIS III rail system – an optimized version of the renowned RIS II rail that was developed by SOCOM. The RIS III rail system is lighter than the RIS II but still provides extreme durability, and multiple M-LOK attachment points allow for the installation of tactical lights/lasers, vertical grips, and other M-LOK compatible accessories. The RIS III incorporates the 6-Bolt, Bolt-Up system, an attachment that is strong enough to withstand the recoil from an M203 grenade launcher. Another notable upgrade is fully ambidextrous controls including the safety selector, bolt release, and charging handle to allow both left and right handed to operate the rifle without moving their dominate hand from the grip. In addition, the MK18 RIII features a 10.3” chrome-lined, heavy phosphate-coated Government-profile barrel for excellent maneuverability and durability.
