It's really straightforward when you look at the structure inside the front of the handguard. The hard part is getting tools in there. I didn't have a dremel, but that would make things much easier. If I wasn't trying to go super cheap, I'd have just gotten a MI keymod 2-piece rail. The Magpul hg is fine, it's just a little bulkier than I'd like.
