Daniel Defense DD4 M4A1 RIII | 5.56 NATO | 14.5″ | MFG# 02-191-10613-047

The Daniel Defense DD4 M4A1 RIII is a purpose-built AR-platform rifle that pairs operator-grade ergonomics with a documented cold hammer-forged 14.5″ M4-profile barrel and a mid-length gas system for smoother cycling. It features a 12.5″ RIS III M-LOK handguard, a fully ambidextrous lower, and a pinned-and-welded Daniel Defense flash suppressor. For a practical optic under $1,000 that complements the rifle’s intended use, consider a Vortex Strike Eagle 1-6×24 or a Vortex Viper PST 1-6×24, both of which balance close-quarters speed with mid-range accuracy.

This rifle suits precision-oriented range training and practical competition shooting where reliability, control, and modularity matter.
