Title: AR flash suppressor
Post by: hookr88 on May 03, 2014, 10:02:26 PM: A question for all you folks who build AR's. I have to remove my flash suppressor to swap gas blocks, can I reuse the crush washer or should I by a new one? The barrel is straight from the manufacturer and has never been fired if that matters. Thanks.

Post by: kbrowne14 on May 13, 2014, 08:03:06 AM: I've reused the crush washer with no problem. I bought a new one to put on, but when I did, the hider would not line up to where it should have, I would have had to crank on the hider way to hard, so I just put on the old one and it was fine.

They need to be fitted. The easiest way is to put a piece of sand paper on a hard flat surface and work the washer on the sand paper, every once in a while installing it with the flash hider until it fits and lines up correctly. Depending on how the hider fits will depend on how much material you have to sand away. When I did this with OEM parts my hider was about 1/4 turn off and it took a bit of sanding to fit it correctly but was easy to do. :twocents:

There may be other ways to do it but this way worked perfect.

Best flash hider on the market. Made in WA! I can tell you that i have had an AR fired with in 3 feet of my face and i saw NO light at night... Pretty sure it doesn't need to be indexed, even if it does i doubt you would notice unless you are wearing night vision!
