Hello, all. I bought my first AR on Tuesday, which as the title implies, is an M&P15T. I'm wondering, though, if anyone knows how to remove the new free-float quad rail that S&W is using now. In the owner's manual it talks about how to get the Troy Industries rail off, but this isn't a Troy rail. All I've been able to find so far on the internet is a few vague references to the fact that S&W isn't using Troy rails and sights on the Tactical any more. If anyone could help me out, I'd appreciate it! Thanks.
