The Daniel Defense DDM4 Rail, found on many DDM4 firearm configurations, features an optimized one-piece, free-floating architecture.

This design results in the ergonomics and proven durability users demand while maintaining the lightweight characteristics they expect from Daniel Defense.

The DDM4 Rail’s ergonomic design allows operators to maintain better control of the firearm.  Limited rotation QD swivel attachment points are located at the front and rear of both sides of this rail system for tangle-free attachment for slings.

A continuous picatinny rail on top provides the rail real estate for sights and accessories.
