The DD4 RIII features the new RISIII rail, modeled after the proven RISII. The RISIII offers M-LOK compatibility while retaining the same 6-bolt, bolt up system and M203 mounting ability(12.5", 13" rails only) as the SOCOM approved RISII. Additionally, the RIII now includes a fully ambidextrous lower receiver for ease of use for both left or right handed shooters.
The DD4 RIII M4A1 includes a 14.5" cold hammer forged, 4150 CMV, chrome lined barrel for accuracy and durability.
