Using washers to install muzzle devices has always been a special sort of self-torture that the Armorer had to endure. The designers at JP Enterprises have found a way to get us all out of the dungeon once and for all. They have redesigned the basic crush washer to create their Double Crush Washer. Add a touch of magic where metallurgy is concerned, and you have the best looking, easiest to use washers on the market.

The JP Washer automatically centers for a smooth, even crush. That gives you even tension throughout timing. Consistent tension and a minimum of a full turn past contact give you the advantage you need to properly time any muzzle device you install with washers.

The JP Double Crush Washer hugs the outer diameter of the barrel threads so it’s simple to keep your parts centered on the barrel. Expansion on application keeps things from binding up so you can remove a device applied with JP’s washer much more easily than others.

Of course, we don’t want to forget the cosmetic advantages of using the JP washer. Your installation will be symmetrical without fail, and the profile after crushing will be almost flat. There has never been a better-looking installation with a traditional washer. JP Enterprises offers the Double Crush Washer in stainless and black finishes so you can choose the right color to blend in with your specific build. Yes, JP Enterprises brings you these simple, essential products with both looks and brains. It’s about time.

    JP has been my answer for many applications, but this little piece everywhere I found cost more to ship than it did to buy, but not with wing tactical. Best price I found to my door, as for the crush washer it was perfect and stupid easy to index.

  • Perfect and Best washer

    Got the stainless to go with a 20” stainless fluted barrel and VG6 Gamma 556 bead blasted compensator/muzzle brake. Tightened right up and makes a nice transition between the barrel and compensator/muzzlebrake.
