The Daniel Defense DD5 SBR .308 Win puts the full-size DD5 battle rifle into a shorter package with a 12.5-inch cold hammer forged barrel (Daniel Defense part no. 02-088-06071-047). Daniel Defense chambers it for 7.62x51mm and .308 Winchester and runs a mid-length gas system with a user-adjustable gas block, so the rifle feels consistent suppressed or unsuppressed. Its 4-Bolt Connection System greatly increases the contact area between barrel and upper receiver, which Daniel Defense credits for accuracy closer to a bolt gun. A DLC-coated bolt carrier group, fully ambidextrous controls and the Linear Compensator round it out. It is the choice for a shooter who wants .308 power in a rifle short enough for a truck or a hallway.
