Daniel Defense DD5 V4 Gen II 7.62x51mm NATO 18" 20+1 - Never Fired w/Case
The DD5 V4 provides users of the Daniel Defense semi-automatic platform even greater long-range precision shooting capability. These gains in ballistic efficiency help the modern shooter stretch the effective range out to 1,000 meters or more. This highly accurate and durable rifle includes an adjustable gas block that allows for a consistent feel whether shooting suppressed or unsuppressed. The perfected bolt carrier group reduces overall recoil impulse and is easy to maintain and operate in all conditions.
