Conceived for the 5.56 NATO cartridge, the Yankee Hill Machine Phantom Comp/Flash Hider’s 5-port design helps to mitigate dust signature when shooting from the prone position by eliminating downward facing ports. Unlike the YHM-28-5C2, this device features a smooth face for those who may not prefer aggressive end cuts.

  • Crush washer included
  • 1/2x28 thread pitch
  • Smooth end cuts
  • 2.2" Overall length

Fits and works fine just fine! Looks good too.

Good stuff


Great visit. Mike was super helpful in answering some questions when I dropped by to pick up the item. It was nice to have someone explain some answers to my questions as opposed to lecturing me like the newbie I still am. Will be ordering all of my items through these guys from here on. Thanks!

Great Product


Great, reasonably priced flash hider with crush washer included. The service from PA was fast and accommodating as well...

Great flash ok comp


I bought this to pin and weld onto a 14.5" barrel. As a flash it works well and as a comp it is a lot better than a standard A2 flash.

I had questions so I called Primary Arms on the phone and received excellent information and advice. Thank you very much for the assistance. TF
