Availability: In Stock
The Fortis RED STS is a 5.56 muzzle brake engineered for shooters who demand both performance and durability. Built from 303 stainless steel, this brake is designed to manage recoil and keep your sight picture steady—whether you're running competitive three-gun courses, training at the range, or drilling from a carbine platform. Fortis Manufacturing built the RED around real-world feedback from military, law enforcement, and competitive shooting communities, then validated it under full-auto fire to ensure it performs when it matters.
The 1/2x28 threading makes it compatible with most modern 5.56 platforms. It ships with a crush washer for secure installation and is manufactured in the USA. The RED is also compatible with common control shields, so it integrates cleanly into your setup without requiring additional adapters.
If you're looking for a muzzle brake that combines proven engineering, versatile compatibility, and American-made quality, the Fortis RED STS delivers straightforward recoil management without the hype.
