SureFire Shim Kit for SF3P / SFMB / Warcomp-556, 1/2-28 Thread

Description

The SureFire 1/2-28 shim kit is the essential accessory for anyone installing a SureFire SF3P, SFMB, or Warcomp-556 muzzle device. Proper indexing of your muzzle device ensures optimal performance, correct port alignment, and a professional-grade installation every time. This comprehensive kit from SureFire includes everything you need to get the job done right, packaged conveniently and ready for your next build or upgrade.

Key Specifications

This SureFire 1/2-28 shim kit is manufactured from high-quality stainless steel, ensuring long-lasting durability and corrosion resistance. The shims feature an outer diameter of .700 inches and an inner diameter of .510 inches, precisely engineered to fit 1/2 x 28 TPI threaded barrels. The kit is compatible with barrels chambered in .22 caliber, 5.56mm, and 9mm. Inside, you’ll find 12 individual shims of varying thicknesses, giving you the flexibility to achieve the exact alignment your muzzle device requires. A tube of Rocksett high-temperature thread locker is also included to ensure your muzzle device stays securely in place once properly indexed.

Performance & Ballistics

While a shim kit doesn’t directly affect ballistic performance, it plays a critical role in how your muzzle device functions. A properly indexed flash hider, muzzle brake, or compensator ensures that gas ports, tines, and baffles are oriented exactly as designed. For the SureFire Warcomp-556, correct indexing means the compensating ports direct gases upward to counteract muzzle rise, delivering the recoil mitigation and flash reduction the device was engineered to provide. Similarly, the SF3P flash hider and SFMB muzzle brake rely on precise alignment to deliver consistent flash suppression and recoil control. Without proper shimming, your muzzle device may be canted or misaligned, potentially degrading its effectiveness and the overall shooting experience.

Intended Use

The SureFire 1/2-28 shim kit is designed for AR-15 platform rifles and other firearms equipped with 1/2 x 28 threaded barrels in .22 caliber, 5.56mm, or 9mm. Whether you’re building a new rifle from scratch, upgrading your existing muzzle device, or reinstalling a SureFire suppressor mount adapter, this shim kit ensures a precise fit. It is an indispensable tool for competitive shooters who demand exact muzzle device alignment for consistent performance, law enforcement and military professionals who rely on their equipment to function flawlessly, and home builders and hobbyists who take pride in a properly assembled firearm. The included Rocksett adhesive adds an extra layer of security, preventing your muzzle device from loosening under the stress of repeated firing while still allowing removal with heat when necessary.
