I wouldn't, they are inexpensive, just pick up a new one and know it is going to be okay.

I buy them 10 at a time on Ebay for about $6.00, much less expensive than I can find them locally, around my area they want like $5.00 each.

It is entirely possible that you can reuse it. Give it a shot. If you can time your muzzle device and it crushes and holds within spec ... well it works.

Can the crush washer in between the barrel and the flash hider be reused? It is not designed to be re-used. |

It is amazing, people come on here, ask the right questions, get the right answers based on others experiences, the complete throw the baby out with the bath water.
Amazing. 10 washers for $6.00 bucks, Why ever ask the question, if all you are going to is question the answer? |

Some people will also re-use roll pins, or stretch out a compressed spring. Just because it works sometimes for a limited time, doesn't mean you should do it. Got an emergency end of the world scenario going on? Do what you have to do. Living in the lap of first world luxury? It's meant to be replaced, not re-used.

Tired it before, however I ended up buying another crush washer. All the "give" was used up in it.

If a crush washer is designed to crush when installed then it is pointless to reuse when using a md that requires timing. I reused once on an AAC brake and it worked fine. $5 is cheap insurance tho on not rattling your device off. |

If it was barely crushed originally and is not being reused back on the same barrel/device it came off of it should work fine as long as the device times and is within torque spec. That said, you can buy a new one for the cost of a couple rounds of ammo so why bother. |

Because buying them 10 at a time is not an answer to the question. Can they be reused ? yes ,if they have enough material to crush within specs. Is it easier just to buy 10 at a time and just replace the used washer ? yes it is easier. Quote HistoryQuoted:

He got the answer to his question in my first post, NO, it is not recommended to reuse a crush washer, that is the correct answer. Do some people do it, yes against the recommendation that they not be reused. Yes, it is easier, as it is recommended to use a new washer when reinstalling a muzzle device. When I can buy them for $0.60 each why worry about it? |

Thanks for the input, I just got a new barrell and was really wanting to get it on the rifle and try it out but I will wait to get a new washer.

I have never seen a used one that has any "crush" worth mentioning. |

Can a crush washer be reused? Probably. Is it a good idea? Probably not.
If the crush washer got good and crushed when it was first installed, it's not going to have much "anti-crush" left, so it won't hold your muzzle device very well, if at all. I've come across crush washers that were not all the same thickness, which meant that sometimes a "brand new" crush washer won't let you time your device. I'm determined to have a few on hand just because. |

I've reused them. If they still have enough crush to time the muzzle device within spec then yes if you have only taken them off once or twice (or 6 times
 ).
I've bought quite a few PSA uppers this year and the first thing info is change the handguard cap. I've reused the crush washer every time. |

I couldn't tell you how many times I've reused crush washers. Never more than once after the initial "crush." Did it today actually when I removed and replaced the FSP on my 16". I just recently purchased a Surefire procomp 5/8-24 for my Gunsite scout and was reading the instructions that came with. It stated that you shall go more that 40(?) and no greater then 450 degrees when clocking the muzzle device. It's my rifle and I've never had a problem with doing it. Hell, there's no telling how much money I've saved on crush washers considering how fickle I get sometimes.
My only recommendation would be to ensure you have the upper secured in the vice by either a clam shell or 2pc vice block set. A lot of torque can be thrown at the upper when working on the muzzle. |

A lot of torque can be thrown at the upper when working on the muzzle. BTW, always clamp your barrel in some wooden blocks when applying torque to the muzzle device, never allow that torque to be applied to the barrel/receiver interface. Clamping the receiver instead the barrel is not kosher and risks shearing off the little pin on the barrel extension. - CW  " />
