Brownells 75th Anniversary - A Shooting Heritage
Menu

Complete your Retro build with the Brownells Improved 3 Prong Flash Hider

Complete your Retro build with the Brownells Early 3 Prong “Duckbill” flash hider.

The “Duckbill” flash hider was found on some of the earliest AR-15 rifles such as the Colt Model 601 used by the US Air Force.  These were eventually phased out due to the lightweight prongs bending.  Looks great at home on a Retro rifle, or any AR-15 of your choice.

  • Original, Early 3 Prong “Duckbill” design
  • Phosphate finish
  • ½-28 threads
  • Modeled directly off of original part

Build the proper 601 or Retro rifle of your choice with an Early 3 Prong Flash Hider.

This muzzle device does not have wrench flats to install. A strap wrench or 3 prong armorers wrench is needed to properly install.
