Daniel Defense DDM4 V5 in 300 AAC Blackout Finding its Way to Shelves

Daniel Defense announced their intentions to develop a carbine in 300 AAC Blackout late last year on the verge of SHOT Show 2012, where they were displaying an early model DDM4 V5 chambered in 300 BLK with their Omega rail system.

A few of these were produced for sale, both complete rifles as well as assembled uppers, although availability has been spotty at best. But now, along with a handful of other DDM4 rifles, Daniel Defense is re-launching the DDM4 V5 in 300 AAC Blackout. These new DDM4s have a few changes, both functional and cosmetic.

The biggest change is the new rail system. Instead of the older Daniel Defense Omega rail, they will use the newer, lighter-weight and more compact DDM4 quad rail. This rail has been redesigned so the 3-, 6- and 9-o’clock rails are all closer to the barrel, resulting in a more slender handguard while maintaining the length and volume of rail of its predecessor.

The new rail is also easier to install and remove with their new “Bolt-Up” mounting system. The other changes include a redesigned front sight block and custom flash hider.

It isn’t much of a surprise for Daniel Defense to continue on making a carbine in 300 AAC Blackout. This little cartridge that could is really winning hearts and minds for its performance inside 300 yards. If you have largely ignored the 300 BLK or considered it a novelty or niche chambering, you may want to reconsider.

The 300 AAC Blackout delivers 7.62x39mm performance from the AR platform. It does this by shortening and necking a .223 Remington case for a 7.62mm bullet. Because the case head and most of the body remains identical to .223 Rem./5.56 NATO, it is fully-compatible with existing bolts and magazines. The cartridge performs well down-loaded to subsonic levels with heavy projectiles, making it a very easy-to-suppress chambering as well. Other specifications include:

  • Indexed, mil-spec upper with M4 feed ramps
  • 16-inch barrel with a 1:8 twist
  • carbine-length gas system
  • mil-spec, MP testes, staked gas key
  • rail covers and forward grip included
  • weight: 7 pounds, 1 ounce

If you’ve all but given up on laying eyes and hands on a Daniel Defense AR chambered in 300 AAC Blackout, now’s the time to start searching again.
