Brando's Review of Daniel Defense M4A1 FSP Rail Interface System RIS II

Installed in conjunction with a Colt 14.5” SOCOM heavy barrel. Attaches to the receiver nicely, retains your FSP, plenty of space for attaching extras, etc. Was my first DD rail and bought for a specific purpose, but after installing and handling it, I think I’ll check out their other rail offerings for future projects. Thing is built like a tank!
Best Used for:
  • Front sight post
  • 14.5 barrels
