SUPPRESSOR PARTS

The Breek-LOK 3QD QD Suppressor Attachment system redefines quick-detach mounts, delivering unrivaled speed and simplicity. Its streamlined profile integrates seamlessly with any firearm for enhanced aesthetics and performance.

The Breek-LOK 3QD Sentinel Caged Flash Hider mitigates muzzle flash by dispersing and redirecting gases, reinforced by internal threads that outperform standard flash hiders. This reduction in flash preserves a clear sight picture and prevents temporary blindness in low-light settings. Closed prongs eliminate snagging, remove the notorious “ring”, and bolster overall strength. The low-profile design maintains a clean, streamlined appearance on any setup.

1. Properly mount your silencer to the host firearm
2. Insert Suppressor Alignment Check Rod down bore of the silencer and into the host firearm bore until the end of the rod is flush with the end-cap of your silencer
3. Observe alignment and confirm rod is positioned near the center of the silencer bore (refer to images above for examples of proper alignment and misalignment)
4. Host firearm may need to be rotated around bore to confirm alignment due to tolerance between the bore and check rod.

Piston are H900 heat treated with a rust inhibitor. Please note, color and color pattern will vary due to the heat treatment.

Silencerco's 3-Lug Muzzle Device fits on to your barrel allowing you to attach your suppressor. This model is compatible with .9mm firearms with 1/2''x36 threads.

Silencerco's 3-Lug Muzzle Device fits on to your barrel allowing you to attach your suppressor. This model is compatible with .45 ACP firearms with .578"x28 threads.

The ASR Flash Hider is compatible with our ASR (Active Spring Retention) Mounts. The ASR (Active Spring Retention) Mount is a quick attach/detach system for almost all SilencerCo suppressors. The simple one-hand-on, one-hand-off mounting system is compatible with all ASR Muzzle Devices to promote ease of transfer from one silencer to another. Once shouldered, the locking ring ensures the silencer won't rotate or work itself loose under a heavy firing schedule. The patent-pending resonance suppression effectively eliminates the tuning-fork effect common with competing 3-prong Flash Hiders.

Constructed of 17-4 PH stainless steel, the Taper Mount EZ-Brake™ features 6 radial slots which provides effective recoil mitigation. The Taper Mount EZ-brake™ weighs 2.0 ounces, making it one of the lightest mounts available for the Taper Mount Interface. The lighter weight reduces suppressor system weight while making the host firearm barrel lighter and more responsive to the shooter. The EZ-Brake™ does not require timing and will interface with a 13/16" standard socket wrench for installation.

SilencerCo's 3-Lug Mount is a quick-attach mounting option for guns with fixed barrels. It features a shorter overall length and is compatible with Octane, Omega K and Hybrid 46. This model is compatible with 3-lug 9mm Luger barrel.

SureFire Suppressor Adapter/Muzzle Brake, fits M4 / M16 weapons and variants with 1/2-28 muzzle threads. It greatly reduces both recoil impulse and muzzle rise so that the weapon tracks straight back to keep you on target for faster shot-to-shot recovery. The patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects. Precision machined from US mill-certified heat-treated stainless steel bar stock including high-precision single-point cut threads for optimum thread interface the SFMB-556-1/2-28 muzzle brake has a black Ionbond DLC coating to provide maximum protection under harsh environmental conditions and to facilitate cleaning even after extreme use. The SFMB-556-1/2-28 also serves as a rock-solid mounting adapter for SureFire SOCOM Series 5.56 mm Fast-Attach suppressors. A rear labyrinth seal minimizes potential carbon buildup in the indexing system and facilitates suppressor removal after extended firing.
