  • Strike Industries Cobra Billet Aluminum Trigger Guard - MSR Arms
    Form meets function with the Strike Industries line of Aluminum trigger guards. Not only does the sculpted, billet aluminum trigger guard make your rifle stand out from the pack, it also provides real added value over the competition. The Cobra’s “hood” provides a hard index point off the trigger for safety, and a convenient rest that is optimally placed for rapid re-engagement. The Fang feature from our popular polymer trigger guard is retained to help guide the magazine for faster, more consistent reloads.
  • The Strike Industries King-Comp features a large dual chamber design, which was engineered to reduce felt recoil and help reduce the side concussion with the specifically angled gas ports. The King-Comp is a great alternative if you're looking for a cross between a compensator and a muzzle brake or effective “combo” muzzle device.
  • The Strike Industries Oppressor represents the next evolution in concussion reduction devices.  Typical concussion reduction devices simply sleeve the brake, with a simple open end to redirect gasses. The OPPRESSOR is compatible with the SI muzzle devices to include: Venom-FH, Checkmate Comp, King Comp, MK-9 Comp, J-Comp Gen2, Sierra Comp, and Triple Crown Comp. While this does accomplish reducing side concussion, braking performance becomes reduced as well.   Designed with computer aided flow dynamics, the SI Oppressor provides a no compromise solution for redirecting the overpressure produced by aggressive brakes and compensators.  Advanced internal geometry actively draws the gasses out and thrusts the gasses forward through vents to accomplish linear braking in order to retain more braking efficiency.  Using a proprietary quick detach mounting system, the Oppressor can be rapidly installed before transitioning to prone shooting positions, or for indoor use. COMPATIBILITY: Only with SI muzzle devices which include: Checkmate Comp, Cloak Flash Hider, JCOMP, King Comp, Mini King Comp, Triple Crown, Venom Flash, Hider Sierra Comp and Ferfrans Muzzle Brake.
  • The advanced SureFire SureFire 3P Eliminator three-prong flash hider features a patent-pending design that greatly reduces muzzle flash — typically greater than 99%—when compared with a plain muzzle.

Precision machined from US mill-certified steel bar stock—including high-precision single-point cut threads for optimum thread interface—the SureFire 3P Eliminator 556 muzzle brake has a black Melonite finish that provides maximum protection under harsh environmental conditions and facilitates cleaning even after extreme use. SureFire flash hiders are individually inspected for concentricity and alignment and are covered by SureFire’s No-Hassle Guarantee.

    The revolutionary SureFire WARCOMP flash hideris the world’s most shootable flash hider. Its patent-pending design provides three valuable functions:
    • It provides over 99% reduction in muzzle flash compared to a plain muzzle, which helps to conceal the shooter’s location and preserve his dark-adapted vision.
    • It virtually eliminates muzzle rise, which enhances monitoring target reaction and staying on target for faster follow-up shots.
    • It serves as a rock-solid mounting adapter for all SureFire SOCOM Series Fast-Attach® suppressors, which share the same basic design as our SOCOM556-RC model, which placed first in the most extensive and rigorous suppressor testing ever conducted by US Special Operations Command.Precision machined from US Mill-certified heat-treated stainless steel bar stock — including high-precision single-point cut threads for optimum thread interface — features an Ionbond DLC coating to provide maximum protection under harsh environmental conditions and to facilitate cleaning even after extreme use.When used in conjunction with a SureFire SOCOM Series Fast-Attach suppressor, the WARCOMP provides multiple bearing surfaces to ensure superior suppressor alignment and prevent any ringing of tines inside the suppressor. A rear labyrinth seal mitigates gas leaking from the back of a suppressor, minimizes potential carbon buildup in the indexing system, and facilitates suppressor removal after extended firing. Every SureFire WarComp is individually inspected for concentricity and alignment.
    For rock-solid mounting of a SOCOM Series suppressor, unparalleled flash reduction, and minimizing muzzle rise, there’s literally nothing like a SureFire WarComp—the world’s most shootable flash hider.

    SureFire Warden Direct-Thread Muzzle Device - MSR Arms
    The SureFire Warden Direct Thread Blast Regulator for 5.56 and 7.62 mm weapons is engineered to direct the concussive blast of the fired round forward of the weapon system without venting gas to the side, as seen with standard muzzle brakes. This aids in reducing the over-pressure felt by others immediately to the left and/or right of the shooter’s firing position. It also limits any dust signature from the weapon when fired from a prone position. The Warden enhances the refined appearance of any weapon with a 1/2-28 or 5/8-24 threaded barrel, protecting the barrel’s exposed threads from damage or fouling in lieu of a flash hider or muzzle brake. . Unlike sound suppressors, Wardens are not NFA devices and are available wherever SureFire products are sold, without any of the restrictions associated with suppressors.

  • The CAGE is the pinnacle of concussion reduction technology. Its primary essential task was to disrupt side concussion while keeping or enhancing the characteristics of the Gamma and Epsilon series of muzzle devices. It accomplishes this with ease. The CAGE does not use a large tubular construction because gas dynamics used for muzzle brakes do not operate efficiently when transferring energy into them. Instead it features a close wrap fit. This allows the CAGE to distribute the gases in a manner conducive to both muzzle control and concussion disruption. The sides of the CAGE utilize a series/pattern of small holes which move over the chambers of the Gamma and Epsilon devices. This allows the gasses to expend energy more uniformly and slows them down while moving through the porting thus disrupting horizontal concussion AND allowing the muzzle brake to have more time to influence the gaseous escape through all the ports. This leads to an extremely smooth recoil and zero muzzle flip by “bleeding off energy” rather than abruptly losing energy.
  • The Delta 556 was designed as an affordable device that embodies the VG6 passion for performance. The Delta 556 maintains great muzzle control characteristics through the large linear ports. This also gives it spectacular flash suppressing characteristics. The Delta 556 contains no chambers so gas is expelled more forward which reduces the concussion to the shooter although recoil mitigation will feel similar to that of an A2 birdcage. This is a great all around device for tactical, competition or recreational shooters at a very affordable price.
