Maple Ridge Armoury Defiant Brake - 1/2" x 28 Thread

A compact, functional brake that avoids the need for top vents by the slightly angled impact faces. The parallelogram-shaped slots are located slightly above the centreline to provide a larger surface area on the bottom side, to provide even more downforce on your muzzle!

  • Choice of .30 cal (5/8" threads) or .22 cal (1/2" threads)
  • AISI 4140 steel
  • Reduces recoil and muzzle rise
  • Low-glare nitride finish has a dark slate grey colour
  • Made in Canada
  • Includes crush washer
  • Weight: 2.6oz
  • Dimensions: 2.5" x 0.85"

Model: Maple Ridge Armoury MRADB223

We recommend a screwdriver with a few wraps of duct tape around the shaft - insert through the 'gills' of the brake and then twist on to crush the washer and keep it all straight and tight. Just ensure that you don't turn too far - if you back off you will need a new crush washer! See pic for correct install orientation.

Spare crush washers and spare jam nuts available.
