Caliber5.56X45 NATO



The Daniel Defense M4 Carbine, V3 Upper Receiver Group is built with a Cold Hammer Forged 16” Government profile barrel with a Mid-length gas system. It comes installed with our proprietary front sight base 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 having them at Mid-length offers a longer sight radius for greater aiming precision. It also allows for a longer rail, the DDM4 Rail™ 9.0 for attaching accessories. 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.
