The DD5 V5 Upper Receiver Group chambered in either 6.5 Creedmoor or .260 Rem. provides users of the Daniel Defense semi-automatic platform even greater long-range precision shooting capability by featuring two of the top short action cartridges available for today’s modern long range shooters. Whether you want to upgrade your DD5 V1 or V2 or have an alternative caliber option for your V3 V4 or V5 both the .260 Rem. and the 6.5 Creedmoor take 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 upper 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 - Backward Compatibility with DD5 V1 and V2 - 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 - Bolt is designed with enhanced extractor geometry and dual ejectors for reliable cycling - 20 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 - Materials & Construction - UPPER RECEIVER: CNC Machined of 7075-T6 Aluminum Type III Hard Coat Anodized - BARREL: DD Proprietary Steel Cold Hammer Forged 1:8 (6.5 Creedmoor) 1:7 (.260 Rem) 20 S2W Profile Rifle +1 Gas System Chrome Lined Mil-Spec Heavy Phosphate Coated - GAS SYSTEM: User-Adjustable Gas Block CNC Machined of 4140 hardened steel and Mil-Spec Heavy Phosphate Coating Rifle +1 Direct Impingement - MUZZLE DEVICE: Daniel Defense Superior Suppression Device 17-4 PH Stainless Steel Salt Bath Nitride Finished - HANDGUARD: Daniel Defense DD5 Rail 15.0 CNC Machined of 6061-T6 Aluminum M-LOK Attachment Type III Hard Coat Anodized - Made in the USA! - Mounting System: M-LOK - Caliber: 6.5 Creedmoor - Gas System: Rifle + 1 - Barrel Length: 20 - Barrel Profile: S2W [Strength-to-Weight] - Product Weight: 6.5 lbs
