NcSTAR AR-15/M4 Muzzle Brake with Crush Washer

Out of stock

This is simply a nice basic upgrade for your birdcage. The finish aint machined, it's rougher like a casting, cheap but she works.


  • AR-15/M4 Muzzle Brake with Crush Washer
  • Screws onto standard AR-15/M4 ½" X 28 threaded barrels (with .223, 5.56 bore).
  • Two chambers with 14 ports that direct the exiting propellant gasses upwards and to both sides to reduce muzzle rise and felt recoil.
  • There are no open ports on the bottom, to reduce the dust signature when firing prone
  • Steel
  • Length: 2.2"
  • Weight: 2.7 oz.

You get:

  • (1) Muzzle device
  • (1) Crush washer (not pictured)

Compatible with:

  • Any .22 caliber firearm with 1/2x28 threads
  • Stainless and blued steel barrels 

Installation Difficulty:

Tools required: Armorers wrench, crush washer, upper or barrel vice, shims or file/sandpaper

Installation notes:

  1. You need to "time" this muzzle device by installing one or two crush washers that will deform as you tighten it to the desired orientation.
  2. Remember to orient the crush washer with the tapered side towards the gun, as shown in the diagram below:
