Daniel Defense MK18 RIII SBR

The Daniel Defense MK18 RIII has less weight, more flexibility, and additional features that make this unmatched short-barreled rifle even lighter, more maneuverable, and more controllable. The MK18 RIII features a fully ambidextrous lower receiver, and Daniel Defense replaced the RIS II rail system with a lighter-weight RIS III rail system that utilizes M-LOK attachment instead of picatinny.

Further Intel:

• 10.3" chrome-lined, heavy-phosphate-coated Government-profile barrel provides outstanding maneuverability & durability

• Fully ambidextrous lower enables shooter to operate important rifle mechanisms without moving dominant hand from rifle grip

• 9.5" RIS III Rail—modeled after the RIS II two-piece handguard developed for SOCOM—features M-LOK attachment for lighter weight
