Daniel Defense DD4 MK18 RIII SBR Rifle 5.56mm 32rd Magazine 10.3" Barrel Black
Product Details
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.
