What's in the Box Daniel Defense DD5 V3 308 Win Semi-Automatic Rifle with M-LOK Rail (1) 20-Round Magazine Daniel Defense Full-Latch Impact Plastic Case Owner's Manual The DD5 V3 builds upon the foundation Daniel Defense established in 7.62 AR-style rifles. 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. Designed around a Cold Hammer Forged barrel with an innovative 4-Bolt Connection System, this design dramatically increases the connection surface area between the barrel and upper receiver for increased rigidity/stability to wring out accuracy traditionally only found in high-end bolt action rifles. The DD5 platforms have upgraded controls like ambi bolt catch, magazine release, safety selector and Daniel Defense enhanced furniture. The DD5 V3 sets a new benchmark in performance for 7.62 AR-style rifles.
