AIM7 Gsh-0.5-58T ASR Muzzle Brake 5/8X24 .30 cal
AIM7 Gsh-0.5-28 ASR Muzzle Brake 1/2 x28″ .223/556/9mm/22LR
The AIM7 Gsh-0.5-28 ASR Muzzle Brake is a 1/2×28 threaded muzzle device designed for compatibility with the SilencerCo ASR (Active Spring Retention) mounting system. This allows for quick attachment and detachment of compatible suppressors, enhancing versatility for shooters.
🔧 Key Features
Thread Pitch: 1/2×28, suitable for calibers like .223 Remington, 5.56 NATO, and .22LR.
ASR Compatibility: Designed to work seamlessly with SilencerCo’s ASR mounting system, facilitating rapid suppressor attachment.
Material: While specific material details for the AIM7 Gsh-0.5-28 are limited, similar AIM7 models utilize SUS303 stainless steel, known for its corrosion resistance and machinability.
⚠️ Important Considerations
Caliber Compatibility: Ensure the muzzle brake’s bore diameter matches your firearm’s caliber. For instance, a brake designed for .223/5.56 with a 9mm firearm can be unsafe due to the larger bullet diameter.
Suppressor Mounting: If you plan to use a suppressor, verify that both the muzzle brake and suppressor are compatible in terms of thread pitch and mounting systems.
🔍 Additional Information
While specific details on the AIM7 Gsh-0.5-28 ASR Muzzle Brake are scarce, similar products like the SilencerCo ASR Muzzle Brake offer insights into the ASR system’s functionality. The SilencerCo ASR Muzzle Brake features a 3-port design to reduce recoil and muzzle climb and is compatible with various thread pitches and calibers.
- Overall: 1.80″
- Outside Thread Pitch: 13/16×16
- Bore Size:0.38″
If your AIM7 muzzle brake is made from SUS303, it’s well-suited for semi-auto civilian use on .223/5.56 rifles, including suppressed setups via the ASR system.
It offers good performance at a reasonable price, but isn’t built for the most extreme military-grade abuse.
Equivalent: AISI 303
| Property | Description |
|---|---|
| Composition | Iron, ~17–19% Chromium, ~8–10% Nickel, ~0.15% Sulfur, ~1% Manganese |
| Machinability | Excellent – sulfur makes it easy to machine (better than SUS304) |
| Corrosion Resistance | Good, but slightly lower than SUS304 due to sulfur content |
| Tensile Strength | Moderate (~500–750 MPa depending on treatment) |
| Weldability | Poor – sulfur causes cracks and inclusions when welded |
| Magnetism | Non-magnetic in annealed condition |

Condition & photos
Item is new unless otherwise noted. Photos show the actual item or a representative sample. Minor handling marks may be present and do not affect function.
Fitment & buyer responsibility
Buyer MUST verify thread pitch, major (nominal) diameter, and thread form prior to purchase. Thread pitch alone is not sufficient. Measure the major diameter with calipers or consult the tube/system manufacturer or a qualified gunsmith. Seller provides nominal specs to assist compatibility checks, but final responsibility rests with the buyer. If you are unsure, message with your tube model, stamped thread, or a clear photo of the tube end and a caliper measurement; we will help confirm nominal compatibility.
Questions/fitment help
Message with your tube model, stamped thread, or caliper major diameter (example: “tube stamp 1.375×24 / major diameter 1.372″”) and we’ll help confirm nominal compatibility. Final verification remains the buyer’s responsibility.
