Integral Muzzle Device (IMD) Thread Mount 1.125×28 ALPHA FOR 5/8X24 30CAL BARREL

  • Material: Made from 17-4 H900 stainless steel, a high-strength and corrosion-resistant material commonly used in firearm components.
  • Function: Combines two functionalities:
    • Integral brake: Reduces recoil and muzzle rise like a traditional muzzle brake, but machined directly into the mount, not a separate attachment.
    • Direct thread mount: Allows for direct attachment of a suppressor (silencer) to the barrel without needing a separate adapter.
  • Benefits:
    • Blast baffle protection: The integral brake design extends beyond the threads, offering additional shielding for the suppressor’s first baffle, which faces the hot gasses.
    • Pinning compatibility: The long “tail” provides a surface area for pinning and securing the mount permanently to the barrel (a legal requirement in some areas).
    • Handguard clearance: The tail length ensures compatibility with handguards that might extend slightly beyond the barrel shoulder.
    • Seamless aesthetics: The tail diameter matches a typical AR barrel for a cleaner look.

This product offers a single, compact unit that combines a muzzle brake, suppressor mount, and potentially a pinning surface for legal compliance.

  • Integral muzzle brakes work just like traditional muzzle brakes. They utilize vents, ports, or baffles to redirect propellant gases exiting the barrel.
  • This redirection helps to counter recoil and muzzle rise, allowing for faster follow-up shots and improved accuracy during rapid fire.


  • Compactness: An integral brake eliminates the need for a separate attachment, resulting in a shorter overall firearm length while maintaining the benefits of a muzzle brake.
  • Reduced weight: By eliminating a separate component, the overall weight of the firearm can be slightly reduced.
    Some shooters prefer the cleaner look of an integral brake compared to a separate attachment.
  • Legality: In some jurisdictions, there are minimum barrel length requirements. An integral brake that extends the barrel length can help a firearm meet these requirements.


  • Limited options: With an integral brake, you’re stuck with the specific design machined into the barrel. You cannot swap it out for a different type of muzzle device.
  • Modification difficulty: If the integral brake is damaged, it can be more difficult and expensive than a replaceable muzzle device.


  • Integral muzzle brakes are often found on hunting or competition rifles where shooters benefit from reduced recoil and faster follow-up shots.
  • They can also be seen on some tactical rifles where compactness and maneuverability are important.

Here are some additional points to consider:

  • Integral muzzle brakes can be louder than traditional brakes due to the design being fixed within the barrel.
  • An integral brake’s effectiveness depends on the firearm’s specific design and caliber.

I hope this clarifies the concept of integral muzzle brakes for firearms.
