Finished building my AR-15 [off-season]

Compared to those Magpul handguards, absolutely. The MI rail is actually about 3 to 4 oz. heavier.

I kinda cheaped out on my last rail system, though. It felt like it was molded from a block of lead. Lol. So this one is actually a bit lighter than what I'm used to. Plus, it's slimmer than a standard quad rail. So it's also a lot more comfortable in my hand.

I've been looking at one of these, I like how they're shaped more like the Magpul with the trapezoid than the circle:

Yeah. I checked out some keymod handguards as well. They're becoming quite popular in the realm of competitive shooting. Those things cost an arm and a leg though. Lol. And, unfortunately, weigh about the same. Hell... even the carbon fiber ones weigh in around 12 oz.
