Daniel Defense DD5v4 in good condition. At the center of the DD5 V4 is an 18-inch Cold Hammer Forged barrel made from Daniel Defense proprietary steel and chrome lined for long service life and consistent performance. Paired with a rifle-length direct impingement gas system and the Daniel Defense 4-Bolt Connection System, the DD5 V4 is built to deliver the accuracy, stability, and repeatability serious shooters expect from a .308 semi-automatic rifle. For shooters running a suppressor, the DD5 V4 includes a user-adjustable gas block with dedicated suppressed and unsuppressed settings. This system is designed to help maintain reliable cycling, reduce excess blowback, and provide a more consistent shooting experience across different configurations. The upgraded DD5 bolt carrier group is superfinished and DLC coated for enhanced lubricity, easier cleaning, and dependable operation in demanding conditions. A built-in buffer helps optimize cycling and improve recoil impulse, while the bolt features enhanced extractor geometry and dual ejectors for reliable function. Finished with the GRIP-N-RIP ambidextrous charging handle with anti-gas features, the DD5 Rail 15.0 with M-LOK attachment, and compatibility with SR-25 pattern magazines, the DD5 V4 is a refined 7.62 NATO rifle built to perform whether suppressed or unsuppressed. Firearm is used with signs of use. I comes as is with 1 magazine and no box or other accessories.
