3FO-S Flash Hider Short Outside Threaded – .223/5.56:

The 3FO-S Flash Hider is machined out of heat treated 4140 then nitrided offering exceptional strength and reliability. The primary function of the 3FO-S diminishes muzzle flash by dispersing and redirecting the escaping gases generated by the fired round, thus minimizing the signature flash produced at the muzzle maintaining your tactical advantage in critical situations as well as keeping your rifle footprint as small as possible.

The 3FO-S has internal threads, a significant design advantage offering even more flash suppression over standard flash hiders. The reduced flash not only helps maintain a clear sight picture but also reduces the chances of the shooter being temporarily blinded in low-light conditions, ensuring optimal visibility and target acquisition. It features a sleek, short profile that integrates seamlessly with your system, maintaining a clean and streamlined appearance.

Breek Arms CASTLE BLAST SHIELD Concussion Device:

Breek’s new slim-line Castle Blast Shield is a muzzle accessory designed to reduce the felt blast noise and concussion for the shooter and nearby operators while still focusing on keeping things compact and lightweight. The blast shield compresses tight to the back of the muzzle brake and directs the noise forward, downrange from the shooter. Anyone nearby on the range or in the field will appreciate the blast being re-directed away from them, improving their hearing and even reducing the burst of gas that can be felt from certain muzzle brake designs when a secondary operator is close.

With the Blast Shield installed it will reduce your muzzle brake’s effectiveness. But if you are shooting alone or just don’t care about the extra noise you are making, it can easily be threaded off and back on as desired. This allows you to pick the benefits you want in any circumstance, without requiring any tools to change anything out.

The 1.26″ outside diameter design allows for the Blast Shield to fit inside most slim-line handguards. And coming in at only 2.15 inches long it adds negligible overall length to your rifle. The 6061 aluminum body and anodized finish of our blast device is made to last. And while it is strong, it is also extremely light weight coming in at a mere 1.6 ounces!

Key Features:

  • 1.26″ outside diameter fits inside almost any handguard, even slim-line handguards
  • 2-1/8″ length adds negligible overall length to most muzzle devices
  • 1.6 ounces – Incredibly light, especially important for a component that is out at the end of the barrel
  • 13/16 x 16 tpi threading – works with ALL of our Outside Threaded Muzzle Devices
  • Design re-directs noise and gasses away from the shooter

Note: The Blast Shield does not protect your ears from the full noise of shooting – it is not a suppressor. Always wear ear protection when shooting!
