"The cutting-edge Daniel Defense DD5 V5 Semi-Auto Rifle raises your expectations for long-range precision from an AR platform. The unique 4-Bolt Connection System offers rock-solid connection of the 20"" cold hammer forged chrome-lined barrel without the use of a barrel nut for greater accuracy. The barrel comes threaded 5/8x24 TPI to accept the included suppression device. Adjustable low-profile gas block ensures a consistent feel whether shooting suppressed or unsuppressed. Bolt carrier group with buffer reduces overall recoil impulse and optimizes cycling. CNC-machined 7075-T6 aluminum receiver set has type-III hard coat anodized finish for rugged durability. Glass-filled polymer pistol grip and 6-position buttstock with soft-touch over molding ensure a solid connection between shooter and rifle.
