Hi, okay so coincidentally, I need help AGAIN with removing a flash hider, but this time its for one that is welded on. I have an Armalite AR180B and I am trying to install a quadrail, but in order to do so, I need to remove the flash hider so I can slip on a few parts required for the accessory rail. I took it to a shop and they told me they would have to completely saw off the flash hider and install a new one. Does anyone else have any experience with this and/or tips? Also, if any one out there can do this at a low or reasonable price please let me know as well. I'm located in the Gresham / Portland area. Thanks.
