Daniel Defense – MK18 RIII™ (10.3” BARREL), Black/FDE

INTRODUCING THE ALL-NEW MK18 RIII™

More control, more flexibility, less weight. That’s what you get with our revolutionary RIII rifles. 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.

TAKING OUR SOCOM RIS II LEGACY INTO THE FUTURE

How do you improve upon our revolutionary two-piece RIS II rail system developed for United States Special Operations Command? By incorporating popular M-LOK attachment and making these hardcore rails even lighter weight while still offering grenade launcher attachment.

FULLY AMBI FOR FULLER CONTROL

More control of your rifle means more control of the situation. Whether you're a righty or lefty, you can easily operate the bolt catch, safety selector, and mag-release button without moving or removing your dominant hand from the rifle's grip.

PATENTED BLAST-PROOF 6-BOLT ATTACHMENT

We use the same battle-tested 6-Bolt, Bolt-Up System developed for our RIS II rails, which provides robust mounting, strong enough to withstand recoil from grenade launchers.

REMOVABLE & COMPATIBLE FOR MORE ATTACHMENT OPTIONS

Versatile two-piece design allows for removal of the lower rail section and easy attachment of M203 (or M320 with adapters) grenade launcher (RIS III 12.5 and 13.0 rails only).

GET A GRIP & LET IT RIP

Ambidextrous GRIP-N-RIP charging handles provide a secure grip and even more flexibility for right- and left-handed shooters. Plus, these ingenious handles are designed with our anti-gas feature to keep gas away from your face and provide a better shooting experience.
