  • 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.

Its patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects.  They also serves as a rock-solid mounting adapters for SureFire SOCOM Series Fast-Attach® suppressors or the SureFire Warden Blast Regulator.
  • The advanced SureFire SFMB-338-5/8-24 muzzle brake, which fits 8.60 mm (.338 caliber) rifles with 5/8-24 muzzle threads, greatly reduces both recoil impulse and muzzle rise and features neutral porting that loads bi-pod legs evenly. Its patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects. The SFMB-338-5/8-24 also serves as a rock-solid mounting adapter for .338 caliber SureFire SOCOM Series Fast-Attach® suppressors.
  • The Stiletto Pro is a pint-sized powerhouse that takes the Stiletto's already legendary performance and durability to the next level. SureFire’s proprietary MaxVision Beam® reflector delivers 1,000 lumens of smooth, shadow-filling LED white light in high-output mode, with a 300-lumen medium output and a 25-lumen low output to suit a variety of tasks. It can be programmed to set the output sequence from low to high or vice versa, and you can always access high output and strobe capability via its tail switch. Its Melonite-coated, reversible heavy-duty spring steel pocket clip keeps the light secure whether you prefer bezel-up or bezel-down storage. Its precision-machined, Mil-Spec hard-anodized aluminum body is sleek and slim for tremendous durability. The Stiletto Pro fits comfortably in any pocket, and it can be drawn and activated with ease.

    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.
