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.
🔍 Material Overview: SUS303 Stainless Steel
The SARH muzzle brake is manufactured from SUS303 stainless steel (AISI 303 equivalent), offering a balance of strength, machinability, 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, suitable for outdoor and range use |
| Tensile Strength | Moderate (500–750 MPa) |
| Weldability | Limited (sulfur reduces weld quality) |
| Magnetism | Non-magnetic (in annealed condition) |
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.
