Product Description

M41 Severe-Duty Muzzle Brake

Three large axisymmetric baffles, each featuring five helical ports, redirect a massive volume of gas away from the bore axis in a counter-clockwise radial direction. This not only provides maximum recoil reduction but also reduces the torsional recoil force associated with heavy bullets and fast twist rates.

High tolerance class-3 threads machined in same operation as bore aperture ensures perfect concentricity; this combined with a progressively decreasing baffle thickness and maximized venting area significantly reduce bullet flight disturbance resulting in less yaw, higher BC, and improved accuracy. Computer FEA optimized for maximum strength to weight ratio and impact survivability.

Precision CNC machined from high strength HTSR 400-series stainless steel bar for superior heat and corrosion resistance. Offered in either an ultra wear resistant DLC (Diamond-Like Carbon) matte black finish, or stainless steel in-the-white, matte finish.

This muzzle brake is designed to fit 5/8-24 threaded barrels and can also be modified by a qualified gunsmith to fit larger thread diameters (up to 3/4" or 18mm).

Does not require any shims/washers for installation.

FEATURES

• Three large axisymmetric baffles allows for symmetrical gas venting - meaning lowest possible bullet yaw
• Digressing baffle thickness reduces baffle/projectile interaction

SPECS

You get:

• 1 × Precision Armament M41 Severe-Duty Muzzle Brake (Model A0400)
• 1 × Shim set (for timing)

Compatible with:

• Barrels with appropriate thread pitches (varies by caliber option, commonly 1/2x28 or 5/8x24)
• A wide range of calibers depending on model selection
• AR-style rifles and precision bolt-action platforms

Installation Difficulty:
Moderate

Tools required:

• Armorer’s wrench or suitable wrench for flats
• Torque wrench (recommended)

Installation notes:

• Uses a shim system (not a crush washer) for precise timing
• Select the correct combination of shims to properly align the ports
• Thread on by hand first to ensure proper fit
• Tighten and adjust using shims until ports are correctly oriented (typically horizontal)
• Do not over-tighten—use shims to achieve alignment rather than excessive torque
• Verify proper bore alignment before firing
• Designed for durability and high recoil reduction in demanding applications
