Description:

Revolutionise Your Comp Installation with Our Double Crush Washers

We've been installing comps with crush washers since the debut of the original Recoil Eliminator. Every one has been a pain to work with and little better than a "necessary evil." There had to be a better way.

Our Double Crush Washers are the way forward. Thanks to a JP original design and careful metallurgy, your next comp installation can be quick and painless. These washers auto-center and provide smooth, consistent crush without struggle.

  • Each washer is good for close to 1 1/2 turns for just-right timing.
  • Made from high-quality black carbon steel.
  • Dimensions: 1/2" x 28, .750 OD.

US Patent Number: 100,041,753

GB Perfect timing without exessive force 10/12/2021

This is the perfect product for timing a muzzle device especially if it only has one correct position per rotation. A little thicker than most, but it actually works. I laid waste to two other crush washers before acheiving satisfactory results with this one.
