Good price. well made

by Sal Cappuccino, Verified Owner from NC, United States Written on September 1, 2021
It’s a crush washer. It does exactly what it supposed to do. I use them on all my barrels with muzzle devices. Yankee Hill is known for quality machining and manufacturing. This is well-made and machined. There’s not too much else love to say. Looks good, feels good and does exactly what it supposed to do.
Pros:
  • well built
  • Machined very well
Cons:
  • None
Best Used for:
  • Putting on muzzle devices
Would recommend: Yes

Works like a champ

Perfect fit for any AR15. The crush washer is great for timing any flash hider. Great value and fast shipping from Optics Planet. I would get it again for my next upper build. Always a pleasure to purchase from here.
Best Used for:
  • AR15

Works great

by Big Ron, from PA, United States Written on November 14, 2016
I installed this crush washer on a custom upper build with a bunch of various parts. everything went together with no issue and it works fine. It's very important to remember that if you're doing a new build you should not reuse the crush washer. It's such a cheap part and necessary to be replaced
Pros:
  • Cheap, effective
Cons:
  • None
Would recommend: Yes

Does what it's supposed to do.

by the sheriff, from NJ, United States Written on September 7, 2016
I prefer a peel washer because a crush washer is very hard to crush. Unfortunately peel washers were out of stock. Other than that it's a simple piece of hardware that does what it's supposed to do. That's why I gave it five stars. There is nothing more to add.
