MK18 RIII URG | 10.3"

MK18 RIII™ Upper Receiver Group

The MK18 RIII™ AR15-style upper receiver group stands out for its compact size, light weight, and exceptional performance. It features a 10.3-inch cold-hammer-forged barrel with an M4 profile, a Daniel Defense flash suppressor, a GRIP-N-RIP charging handle, and a carbine-length gas system.

The model features a 9.5-inch lightweight RIS III rail based on the revolutionary RIS II two-piece handguard rail designed for SOCOM. This rail offers M-LOK mounting points for reduced weight. All Daniel Defense Upper Receiver Groups come standard with an M16 bolt carrier group profile.
