More control, more flexibility, less weight. That’s what you get with the revolutionary DD4 RIII 5.56 16″ rifles. The new DD4 lower receiver is the same you’ve come to love, trust, and expect from Daniel Defense, only now fully ambidextrous. The 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 the 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. If you’re a bad enough dude to want a nigh-indestructible, ambidextrous, free-floated-even-with-a-grenade-launcher, M-LOK compatible rifle, then the DD4 RIII 5.56 16″ is just the one for you.
