The DD5V4 chambered in either 6.5 Creedmoor or 7.62x51mm NATO provides users of the Daniel Defense semi-automatic platform even greater long-range precision shooting capability. The highly popular 6.5 Creedmoor takes advantage of superior ballistic coefficients to offer both flatter trajectories and reduced wind drift at levels normally reserved for much heavier recoiling long action calibers. These gains in ballistic efficiency help the modern shooter stretch the effective range out to 1000 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. - FEATURES: - User-adjustable gas block for reliable suppressed shooting - Superfinished and DLC-coated bolt carrier group makes it easy to clean and operate in all conditions - Bolt carrier is equipped with a buffer for optimized cycling and improved recoil impulse - 18 Cold Hammer Forged proprietary steel chrome-lined barrel for a lifetime of accuracy and durability - Innovative 4-Bolt Connection System to ensure greater accuracy - GRIP-N-RIP independently ambi charging handle with anti-gas features for a better shooting experience - SPECIFICATIONS: - Caliber: 6.5 Creedmoor 7.62x51mm NATO - Barrel Type: DD Proprietary Steel Cold Hammer Forged - Barrel Profile: S2W (Strength-to-Weight) - Rifling Twist: 1:8 (6.5 Creedmoor) 1:11 (7.62) - Gas System Length: Rifle - Bolt Carrier Group: Advanced VAR Stainless Steel Bolt & 8620 Carrier - Muzzle Device: DD Superior Suppression Device - Trigger: DD Mil-Spec - Overall Length: 35 3/8-39 - Weight (unloaded): 8.6 LBS - Rail System: DD5 M-LOK Free-Floating - Magazines: Accepts all SR-25 Magazines
