A 7.62x51mm/.308 win DD5 built for accuracy, reliability and easy suppressor use. 4-Bolt Connection System Most large-frame AR rifles rely on a single barrel nut. The DD5 uses Daniel Defense's 4-Bolt Connection System instead, joining the barrel and upper receiver with four bolts over a larger surface area. The added rigidity improves stability and supports accuracy usually associated with high-end bolt-action rifles. It also makes the free-floating DD5 Rail 15.0 rock solid when you load a bipod or a heavy optic. Barrel and Adjustable Gas The 18 inch barrel is cold hammer forged from Daniel Defense proprietary steel with a 1:10 twist and the S2W heavy profile, then chrome lined and Mil-Spec heavy phosphate coated for long life. The 1:10 twist is well matched to common 150 to 175 grain .308 loads for hunting and target work. A pinned user-adjustable gas block machined from hardened 4140 steel lets you tune the rifle length gas system for suppressed or unsuppressed shooting. That keeps cycling reliable and cuts down the extra blowback many rifles have with a can attached. The Superior Suppression Device on the muzzle is 17-4 PH stainless steel with a salt bath nitride finish. Check your local laws before buying or using a suppressor. Bolt Carrier Group, Controls and Furniture The DD5 bolt carrier group is superfinished and DLC coated for better lubricity, easier cleaning and dependable function in dirty conditions. A buffer built into the carrier optimizes cycling and improves the recoil impulse, and the bolt has enhanced extractor geometry and dual ejectors. The GRIP-N-RIP charging handle is independently ambidextrous and has anti-gas features to help keep gas away from your face when suppressed. The upper and lower are CNC machined from 7075-T6 aluminum, and the lower has an enhanced flared magazine well and a rear receiver QD swivel point. The Daniel Defense buttstock rides on a 7 position 7075-T6 aluminum receiver extension, and both the stock and pistol grip are glass-filled polymer with soft touch overmolding. A Daniel Defense Mil-Spec trigger is installed. Is the DD5 V4 Right for You?
