Add in an ambidextrous safety, flared magwell, and Daniel Defense's rugged and ergonomic furniture, and you have a solid contender for your next rifle.

  • 16" cold hammer forged government profile barrel has been heavy phosphated and chrome lined to MIL-SPEC.
  • Smooth and reliable mid-length gas system balanced with a heavy buffer for smooth recoil.

  • Effective flash suppressor helps tame muzzle flash.

Daniel defense m4v9


Bought my m4v9 in 2014 in Baytown Texas . It now has about 6000 rds through it without any problems it's accurate reliable and light recoiling. What else can you ask for in a rifle.i am thinking about a 300blk and would surly go to the same people to get it .
