Well, technically you're correct. I call it triangular based on the basic shape. It isn't round, like the majority of forends out there.

I might have to alter my correction...in that picture, it looks almost pentagonal.
Nope, because of the top rail, it still had 6 sides...it is still hexagonal

Well, technically when you use a mathematical term like "triangular"...which has a universally defined meaning...it is either correct or incorrect. I guess if you were to cut it in half, you could call the upper half triangular and the bottom half a trough
I got to finger bang a Core15 tac 3 with the midwest industries rail and loved it so much I ordered one myself. The diameter is a mere 1.5" and it's lightweight, felt very good in my hands.

What is the ID? I need one that my suppressor will slip into, and I want as small an OD as I can get that will allow it.
Not sure what kind of suppressor you're running but I would think it would be close if it fit. The link in my other post may have more specs on it.
Although the Core15 tac 3 I just ordered has a 16" barrel with a 15" hand guard so it sticks out just enough to get your suppressor on there.
There is a big move to rail less free floats, and keymod is just one way to attach the mounts. The trend is
to move toward a lot smaller diameter, and the less expensive, the better for a substantial part of the market, because they don't plan on mounting all that much on it anyway.
Entirely why Amy Giselle came up with her EMR free float: http://algdefense.com/12-ergonomic-modular-rail-black.html
A small diameter free float with no rail is the trend, it's going to be interesting to see how much the price on a used quad rail will drop over the next year. It's not all about the specific Keymod feature as it is the diameter and price. I speculate that we could even see the DOD adopting a rail free handguard if the M16 undergoes another type classification.

Thanks that says its 1.3" ID, My GemTech Multimount fits inside my UTG SS, its a 5.5" 9mm with a 9" hand guard. But from the specs, it look like my new ISIS-2 won't quite fit, will know for sure tomorrow after I pick up the can from the dealer. The ID of the UTG SS is about 1.4", the OD about 1.6" on the raised sections where the rails mount.
The UTG is not keymod, but I really only care about as thin as possible with a large enough ID. My 5,56 can is a GemTech Halo which mounts to the A2 flash suppressor so partially under the hand guard is not an option with it.
I'm thinking of going to this with my 16" bull barrel to get a longer sight radius for the offset BUIS.
I like that ALG rail, and at that price I would have bought it instead of the Samson had I known about it. I like the way it attaches better as well.
I almost bought a Midwest Key Mod rail instead of the Samson, but was too cheap to go the extra bucks.
tirod, yeah, after my initial posting i realized it was somewhat misleading and what i was really excited about was half the materials change and the design of the BCM rail. Certainly keymod is a feature that allows it to be super thin and slick. but it is also the alloy that makes it even lighter than other keymod offerings
Yes, the superduper alloys really lighten the load. It's not all about the keymod.
With the 5.56 going light doesn't substantially increase perceived recoil, either, unlike the mountain rifles which drop two pounds but shoot .30 caliber cartridges. There's also the perceived recoil difference of a locked breech vs. self opening action.
Like Walkalong said, tho, price gets involved. A $70 difference is big for some of us when we consider what else can be done with it. It's not that cheap is necessarily better, it's more like the added price of the expensive part has diminishing returns. If we could actually double the performance for twice the money . . . oh well. What price for a 2 oz. titanium and carbon fiber handguard?

Not sure if this would be too fat or too heavy, but the JP Enterprises tubes are apparently 2.0" OD and 1.75" ID. Of course, that makes them somewhat heavier than a 1.5" OD tube, all else being equal.
I have always liked the way the JP tubes look, but I want as small an OD as possible, so I am leaning more toward a Midwest Industries Gen 2 when I can scrape together enough pennies (probably non-keymod). I'd love the lighter BCM rail but the cost is an issue.
