Daniel Defense 02-191-04238-055 M4A1RIII CA Compliant: Precision and Compliance in 5.56mm

Introducing the Daniel Defense M4A1 RIII - an enhanced iteration of Daniel Defense's renowned M4A1 platform, thoughtfully upgraded to deliver superior performance and user convenience. At the heart of this rifle is the exclusive RIS III rail system, an optimized evolution of the esteemed RIS II rail developed in collaboration with SOCOM. This lightweight yet incredibly durable rail system incorporates multiple M-LOK attachment points, empowering users to easily install tactical lights, lasers, vertical grips, and other M-LOK compatible accessories to suit their mission needs.

A standout feature of the M4A1 RIII is its 6-Bolt, Bolt-Up system, specifically engineered to withstand the powerful recoil from an M203 grenade launcher, ensuring unmatched reliability even in the most demanding scenarios.

Designed with ergonomics and versatility in mind, the M4A1 RIII boasts fully ambidextrous controls for the safety selector, bolt release, and charging handle. This enables seamless operation for both left and right-handed shooters, without having to adjust their dominant hand from the grip, ensuring optimal handling and precision in any situation.

The rifle features a 14.5” barrel - identical to the U.S. Military's M4 rifle - but with a pinned and welded 1.5” flash hider, achieving an overall barrel length of 16” to comply with NFA regulations. This balanced configuration offers both maneuverability and accuracy in equal measure.

Furthermore, the M4A1 RIII is equipped with a full-length flattop picatinny rail, providing the flexibility to mount iron sights or an optic of choice, tailored to individual preferences and shooting requirements.

With the M4A1 RIII, Daniel Defense has redefined what a high-performance rifle should be. Engineered to excel in any mission or shooting scenario, this refined platform is a testament to the relentless pursuit of excellence and unwavering commitment to meeting the needs of discerning shooters.
