Rob's Review of Daniel Defense DDM4 300 S, URG, 10.3in, 300 AAC Blackout Complete Upper Receiver w/ Flash Hider

It's a MK18 in .300BLK, product was obviously perfect because Daniel Defense QC is among the best in the business. If you want a very reliable and durable shorty upper in .300BLK, there are not many options better than this.
Pros:
  • Durability
  • Reliability and ease of use
  • QC
Cons:
  • weight
  • cost
