Aim7 Tempest Plus Taper ASR & SARH 2 Port Muzzle Brake 556/223/22
Description
Aim7 Tempest Plus Taper ASR & SARH 2 Port Muzzle Brake 556/223/22
Linear compensators are part of a specialized family of muzzle devices designed to reduce muzzle concussions. The AIM7 linear comp is a prime example of efficient collection and redirection of muzzle gases away from the shooter. This forward redirection significantly reduces the perceived noise levels at the shooter’s ear, resulting in a softer shooting experience. Additionally, by pushing excessive noise and concussion downrange, bystanders also benefit from reduced exposure to muzzle gases.
Aim7 linear compensators have been successfully applied across various shooting disciplines, including:
- Close Quarters Combat (CQC)
- Competitive Shooting
- Varmint Hunting
- Law Enforcement
- Indoor Ranges
Installation
- No Crush Washer Needed: Installation is straightforward without the need for a crush washer.
- Optional Indexing: If indexing of wrench flats is desired, a crush washer or other timing device can be used.

What is a Linear Compensator?
A linear compensator, also known as a linear comp, is a device attached to the muzzle of a firearm that redirects the gases expelled when a bullet is fired. A linear compensator directs the gases forward, unlike traditional muzzle brakes or compensators that direct gases to the sides or upwards to reduce recoil and muzzle rise. This design offers several benefits:
The AIM7 Gsh-0.58t ASR Muzzle Brake is a 5/8×24 threaded muzzle device engineered for compatibility with the SilencerCo ASR (Active Spring Retention) mounting system. It enables quick and secure attachment or removal of ASR-compatible suppressors, providing shooters with greater flexibility and convenience.
🔧 Key Features
- ASR Mount Compatible: Works seamlessly with SilencerCo’s ASR mounting system for fast, reliable suppressor installation.
- Material: Made from SUS303 stainless steel, valued for its corrosion resistance, machinability, and durability.
- Dimensions:
- Overall length: ~1.80″
- Outside thread pitch (for ASR mount collar): 13/16×16
- Bore size: 0.38″ — ensure it is appropriate for your caliber.
⚠️ Important Notes
✅ Caliber Matching:
Always verify that the bore diameter of the muzzle brake is appropriate for your firearm’s caliber. Using a brake designed for .30 cal (.308/7.62) on a larger bore (like 9mm or .338) can cause dangerous pressure spikes.
✅ Suppressor Mounting:
Check that your suppressor is designed for use with a 5/8×24 threaded barrel and is compatible with the ASR mounting system.
🔍 Material Overview: SUS303 Stainless Steel
This muzzle brake is manufactured from SUS303 (equivalent to AISI 303), an austenitic stainless steel known for its ease of machining and corrosion resistance.
| Property | Description |
|---|---|
| Composition | Fe, 17–19% Cr, 8–10% Ni, ~0.15% S, ~1% Mn |
| Machinability | Excellent (better than SUS304) |
| Corrosion Resistance | Good, slightly lower than SUS304 |
| Tensile Strength | Moderate (500–750 MPa) |
| Weldability | Poor (due to sulfur content) |
| Magnetism | Non-magnetic (annealed condition) |
SUS303 is a good choice for civilian semi-automatic rifles and moderate use, but it is not intended for extreme military-grade abuse.
⭐ Summary
The Aim7 SARH 2 Port Muzzle Brake is a precision-engineered muzzle device designed for recoil reduction and improved muzzle control on small-bore rifles. With its 1/2×28 thread pitch and dual-port design, it is ideal for platforms chambered in .223 Rem, 5.56 NATO, and similar calibers. Constructed from SUS303 stainless steel, it delivers excellent durability, machinability, and corrosion resistance. Compact yet effective at 1.650″ overall length, the SARH brake provides shooters with a balance of performance and reliability.
🔧 Key Features
Thread Pitch: 1/2×28 — standard threading for .223 / 5.56 platforms.
2-Port Design: Dual side ports reduce recoil and muzzle rise for faster follow-up shots.
Material: SUS303 stainless steel — excellent machinability and good corrosion resistance.
Dimensions:
Overall Length: ~1.650″
Bore Size: 0.368″ — confirm compatibility with your caliber.
Finish: Stainless steel, resistant to carbon buildup and environmental wear.
📦 Contents of Package
1× Aim7 SARH 2 Port Muzzle Brake — 1/2×28
🔗 Compatibility
Firearms: Barrels with 1/2×28 threaded muzzle
Calibers: Up to .223 Rem / 5.56 NATO (.368″ bore)
Not Recommended: Use with calibers larger than bore size (e.g., .30 cal, 9mm) without professional assessment
🔄 Suppressor Compatibility
The SARH 2 Port Muzzle Brake is designed to work seamlessly with the 13/16×16 ASR Adapter, enabling compatibility with SilencerCo’s ASR (Active Spring Retention) mounting system. This allows fast and secure attachment or removal of ASR-compatible suppressors, giving shooters greater flexibility in both suppressed and unsuppressed configurations.
🛠️ Installation Instructions
⚠️ Safety First: Always ensure the firearm is unloaded before installation.
Prepare the Barrel
Clean muzzle threads of carbon, oil, or debris.
Thread the Brake
Hand-thread the SARH brake until snug.
Align the Ports
Large side ports at 3 and 9 o’clock.
Secure the Brake
Tighten with a wrench an additional ¼ turn past hand-tight, or until properly timed.
Avoid overtightening to prevent thread damage.
Final Alignment Check
Use a bore rod or visual confirmation to ensure no obstruction is in the bullet path.

Aim7 Taper Mount Adapter 1.125″x28
(Fits all Aim7’s ARCHER & APEX tubes)
Fits Griffin pistol silencers, and other suppressors with mount interface inside diameter threading of 1.125×28 such as Silencerco® Octane™, Octane 9K™, Octane 45k™, and Rugged Suppressors® Obsidian™. No proprietary tools required.
ASR (Adaptive Suppressor Ready) 13/16×16 Linear Comp Adapter and Mount, which is designed to be installed midway along a hub/Tube, typically between the hub and barrel tubes—likely for suppressor or muzzle device integration.
Designed for installing in a modular suppressor system,
this is used as a thread adapter and blast-forwarding linear compensator, or just as a spacer/mounting interface
The ASR 13/16×16 Linear Comp Adapter is both a functional mount and a kind of barrel shroud by pushing it forward over part of the barrel, right? That’s a pretty slick setup—dual purpose:
Barrel shroud: It acts like a sleeve, covering part of the barrel to give a cleaner look and possibly protect or reduce heat transfer.
Quick-detach function: Since it’s tied into the ASR system, you get easy on/off with suppressors or comps—super handy if you’re swapping setups.
The fact that it slides forward a bit onto the barrel also probably improves rigidity and alignment, which is especially helpful for QD suppressors. It makes installation feel more solid, and you’re not relying solely on the muzzle threads.
ASR 13/16×16 Linear Comp Adapter Overview:
Overall Length: 0.854″
Unthreaded Section Length: 0.5″
Diameter: 1.291″ – that’s pretty beefy, giving it that barrel shroud vibe when pushed forward.
Threads (Male & Female): 1.125×28 TPI – so it’s a true inline adapter, threading into and accepting matching tube sections.
