Barrel Components

Muzzle Brake
Post Ban muzzle brake

These post ban muzzle brakes are a slip over design that are held on using 4 set screws. Because of the unique design of the Olympic Arms barrels, and the rings behind their muzzles, these brakes work excellently on Oly Arms products.

  • Muzzle Brake when ordered

  • Muzzle Brake; stand alone = $35.00
  • Muzzle Brake; Pistol Caliber = $46.00

  • Gas Blocks
    Picatinny and Round gas blocks
    This is a photo of our gas blocks. These gas blocks both the round and Picatinny Rail blocks are available for all sizes of our barrel contours (Bull, standard heavy, and Eliminator). These blocks are sold separately from the barrels, and can be used on new as well as old Olympic and other standard spec AR style barrels.

    The standard (round) gas blocks are slated to be discontinued and completely replaced by the Picatinny rail gas blocks. Supplied are limited, and your order may be upgraded to the Picatinny rail gas block without notification

    Free Floating
    Tube Handguards
    The F8A Aluminum Handguard
    The F8A, Carbine length Aluminum Handguard.

    The F7A Aluminum Handguard
    The F7A, Rifle length Aluminum Handguard.

    The single most important thing that you can do to improve the accuracy of your barrel other than replacing the barrel, is to add a free-floating handguard assembly. This upgrade does the same thing for your AR as glass bedding does for your bolt action rifle. Free-floating the handguard removes all the outside stress from the barrel as is possible with an AR type rifle, allowing for maximum inherant accuracy of the rifle.

    Please specify length when ordering.

    • F8A, Aluminum handguard for 16" Carbine length barrel = $43.00
    • F7A, Aluminum handguard for 20-26" Rifle length barrels = $52.00
