Daniel Defense DD4 RIS III Complete AR-15 Upper Receiver - 5.56 - 16"

The Daniel Defense DD4 RIS III Complete AR-15 Upper Receiver in black pairs a 16" government-profile barrel with the 12.5" lightweight RIS III M-LOK rail, a precision-built foundation ready for your lower.

Features:

• 16" government-profile barrel, chrome lined, 1:7 twist
• Mil-Spec heavy phosphate coating
• Mid-length-length gas system with pinned low-profile gas block
• Daniel Defense flash suppressor
• 12.5" lightweight RIS III M-LOK handguard
• M16-profile bolt carrier group
• GRIP-N-RIP charging handle
• Black Type III hard coat anodized finish
• Bolt carrier group and charging handle included

The RIS III rail trims weight from the earlier RIS II design while keeping its M-LOK attachment points and 6061-T6 aluminum construction, and the pinned low-profile gas block pairs with the mid-length-length system for consistent cycling on this 16" barrel. The M16-profile bolt carrier group is standard on every Daniel Defense complete upper for added reliability margin.

The 12.5" handguard leaves plenty of room to mount a light, foregrip, or sling attachment without crowding the muzzle end, and the mid-length gas system keeps recoil impulse soft on this 16" build.

Daniel Defense has supplied duty-grade AR-15 rifles and components to U.S. special operations units, law enforcement, and civilian shooters for over two decades, and this complete upper carries that same mil-spec pedigree.
