Yankee Hill 4405MB24 sRx QD Muzzle Brake 5/8x24 9mm Black Steel

The Yankee Hill 4405MB24 sRx Q.D. Muzzle Brake delivers rapid suppressor attachment with precision-engineered recoil control for 9mm firearms. This black phosphate steel brake integrates seamlessly with sRx quick-detach suppressor systems while providing effective muzzle rise reduction during unsuppressed fire.

What Makes This Different

Unlike standard linear compensators, this dual-purpose brake features optimized port geometry that reduces felt recoil by approximately 15-20% while maintaining compatibility with sRx suppressor adapters. The quick-detach mechanism allows suppressor mounting in under three seconds with positive lockup. Black phosphate coating provides superior corrosion resistance compared to standard parkerizing, extending service life in adverse conditions.

Key Features

• Quick-detach suppressor compatibility with sRx adapter systems
• Precision-machined 5/8"-24 TPI threading for secure barrel attachment
• Black phosphate steel construction resists wear and corrosion
• 2.30" overall length maintains compact firearm profile
• 0.9375" diameter optimized for 9mm projectile clearance
• Dual-port design reduces muzzle rise and felt recoil
• Heat-treated steel withstands high round counts

This brake performs effectively across multiple shooting disciplines, from competitive PCC matches to tactical training scenarios. The phosphate finish maintains appearance through extended firing sessions while the steel construction handles rapid-fire strings without degradation. Shooters report improved follow-up shot speed due to reduced muzzle movement, particularly beneficial in multi-target engagements.
