Does not include crush washer. - Radical Firearms A2 Flash Hider

this review may be a bit premature, as I am still discussing this issue with opticsplanet, but mine did not come with a crush waster. Perhaps it is a mistake, perhaps not. Nobody can say for sure at this point.

The flash hider seems well made and has a nice finish to it. It appears to be nitride rather than parked. So if you have a spare crush washer, this is a great hider. If you don't, you risk ordering all your parts, being short a washer, and looking at paying 2-3x the price of a washer just in shipping to order one.....
