Daniel Defense MK18 RIII SBR, 5.56MM, 10.3″, Black
The Daniel Defense MK18 RIII SBR, 5.56MM, 10.3″, Black AR15 style firearm provides more control, more flexibility, and less weight. The new DD4 lower receiver is the same you’ve come to love, trust, and expect from Daniel Defense, only now fully ambidextrous. Our all-new RIS III rail system is modeled after the proven RIS II developed for SOCOM, but now in M-LOK for extreme durability with less weight. It features our hardcore 6-Bolt, Bolt-Up System used on the RIS II, and the same two-part free-float design that never makes contact with the barrel – not even with an M203 grenade launcher installed – so barrel harmonics and accuracy are not affected. The lightweight, heavy-hitting RIII is ready for anything.
This firearm is a regulated item by the National Firearms Act (NFA). Please check with your local and state municipalities for any further regulatory requirements. It is the buyer’s responsibility to make sure they comply with all NFA rules and applicable laws.
