Tactical Modular Ultra Low Concussion (MULC) Muzzle Brake System with Vented Shroud

Our latest Modular Ultra Low Concussion (MULC) Muzzle Brake design combines the proven effectiveness of the Extreme Duty muzzle brakes with critical reduction in overpressure and concussion.

The Modular Ultra Low Concussion Muzzle Brake takes advantage of state of the art Computational Fluid Dynamics software. Designed for specific dynamic goals, the MULC Muzzle Brake tames the stoutest magnums with superior reduction in firing point concussion and overpressure! Built for CQB and Ultra Low Concussion for operators of all platforms from SBRs to long range tactical rifles. The MULC Muzzle Brake does not reduce loudness, it reduces felt concussion (overpressure) from the shooter's position as well as to those nearby by directing shock waves downrange.

The removable Blast Management Jacket ( BMJ ) and included thread protector provides field changeable configuration for adjusting concussion control vs. braking as well as weight and size.

The MULC is offered in a Tactical System configuration with a removable blast management jacket (BMJ) and thread protector for the external BMJ threads when the BMJ is removed.

  • 1/2"-28 threads (.224 bore & smaller)

    Special Offer With This Muzzle Brake

    One Ultimate Rifle Muzzle Lock Nut for $12.49.
    Please specify that you want lock nuts, the quantity and the sizes when contacting us for a total.

    The lock nut is an excellent way to align (clock) and retain your muzzle device. It is reusable, provides positive retention and does not require special tools. Lock nuts help you avoid accidental damage to your rifle during muzzle device installation. Our lock nuts are designed to conceal and protect the barrel just behind the muzzle. The maximum barrel diameter is 0.75".

    These lock nuts are designed to minimize stress on your firearm during leveling (clocking) and installation of your muzzle device. In the photos you can see that when tightening the lock nut and the muzzle device the net torque on the barrel is near zero, unlike shims and crush washers which involve intense torque on the barrel and can require the barrel be secured in a vise.

    A high ratio of the threaded portion of the brake in contact with the barrel to the threaded portion of the lock nut in contact is the key to the combination staying tight. However, thin hex and armorer's wrench jam nuts which meet this requirement are difficult to apply torque to without wrench slippage or special tools.

    The broad wrench flats of the Ultimate Lock Nut make a common pair of adjustable wrenches all you need to install, adjust, remove and replace muzzle devices.

    Choose from these thread sizes:

  • LN5 1/2"-28 thread
  • LN6 5/8"-24 thread
  • LN7 9/16"-24 thread

    Key Features:
  • Easily install, adjust, remove and replace muzzle devices without special tools
  • Dimensions: 0.875" diameter x 0.50" long (fits any barrel muzzle diameter 0.75" and under)
  • Wrench flats are 0.80" apart
  • Black Mil Spec Finish
  • Case Hardened Steel - durable and reusable
  • Protects muzzle and threads
  • Designed in and Made in USA with USA steel!
  • 30 day, 100% satisfaction money back
  • Seller provided no "Additional Terms of Sale"
