Just a heads up. I had to do some grinding to make this fit my Adam Arms upper.

Also, the proprietary tool that is needed to install this rail is no longer manufactured by Daniel Defense and is not sold any where for that matter -- you will need a strap wrench to install. What's more, I'd recommend to use some anti-seize compound on the threads of the handguard for smooth installation
