High-Performance Package: Daniel Defense 02-191-10613-047 DD4 M4A1 RIII Rifle with 32rd Mag IncludedThe Daniel Defense M4A1 RIII from Daniel Defense is a highly refined version of their popular M4A1 platform, offering numerous upgrades for enhanced performance and ease of use. One of the standout features of the M4A1 RIII is the exclusive RIS III rail system, which is an optimized version of the renowned RIS II rail that was originally developed by SOCOM. The RIS III rail system is lighter than the RIS II, but still delivers extreme durability, making it ideal for demanding environments. The RIS III rail system also incorporates the 6-Bolt, Bolt-Up system, which is designed to withstand the recoil from an M203 grenade launcher, providing added versatility for users who require that capability. The rail system also features multiple M-LOK attachment points, allowing for the installation of tactical lights, lasers, vertical grips, and other M-LOK compatible accessories, providing users with ample customization options to suit their needs. The M4A1 RIII is its ambidextrous design, with a fully ambidextrous safety selector, bolt release, and charging handle. This allows both left and right-handed shooters to operate the rifle without having to move their dominant hand from the grip, providing increased efficiency and versatility in various shooting scenarios. The M4A1 RIII also sports a 14.5" barrel, which is the same length as the U. S. Military's M4 Rifle. However, to comply with NFA regulations, the barrel is pinned and welded with a 1.5" flash hider, resulting in an overall barrel length of 16". Additionally, the rifle features a full-length flattop Picatinny rail, providing ample space for the installation of iron sights or an optic of choice, allowing for versatile and reliable sighting options. The M4A1 RIII from Daniel Defense is a top-of-the-line rifle that offers multiple upgrades for improved performance and ease of use. From its durable and lightweight RIS III rail system to its ambidextrous design and compliant barrel length, the M4A1 RIII is a high-quality choice for discerning shooters who demand excellence in their firearms.
