Daniel Defense V1 Upper Receiver Group
The DDM4v1 Upper Receiver Group is built with a Cold Hammer Forged 16” M4 Profile barrel with a Carbine-Length gas system. It comes installed with our proprietary front sight block which is precision CNC machined from a solid billet of 4140 steel. This FSB features a serrated curved design to reduce glare and is salt bath nitride treated minimizing corrosion and wear. Fixed front sights are often regarded to be the most resilient sights and with the DDM4 Rail 12.0™ FSP the operator can still mount a weapon light or aiming device forward of the front sight for optimal ergonomics and a clear line of sight. QD Swivels attachment points are integrated in to the front and back on both sides of the rail for fully ambidextrous sling attachment. Daniel Defense complete upper receiver groups come complete with bolt carrier group and charging handle.
