    I have a beef to pick with BCM.

    After purchasing my 14.5" ELW w/13" KMR rail my Troy quad rail feels like a piece of crap! The lightweight, well thought out contoured design of the KMR has ruined me, I will never be able to go back to a quad rail. So know I have a rifle sitting in the safe that I don't want to use. Oh well, I guess it will be ready for the next panic and find a new home.

    I think somebody already has thought of this kind of mounting several years ago (like 10?) and there is at least one other manufacturer who uses that. Of course details like screw placement (bottom or top) vary, but it is same general idea.

    The screw placement is a critical feature and not just some variance from other designs.

    Screw placement on top is critical for this exact design, because of lack of bottom channel. But it does not make mounting principle any different*. It is just "upside down". Also removable clamping pieces reduce machining or welding (but can be easily lost - so no go for some applications).

    *- unless I miss something extremely crucial by a mile - but I see same barrel nut design and same solution to retain handguard in place on barrel nut.

    Well I guess I mean that had they put the mounting screws on the bottom like some handguards I've seen that have only a pic rail on top, it would be an inferior design in that it pulls the top rail's side walls apart.

    Actually, placing the screws on top of the barrel nut creates significantly different clamping forces than placing the screws underneath because they complete a ring of tension around the nut. When you clamp on the bottom, tension pulls the open gas tube channel down onto the barrel nut, prying it open, which forces the hand guard to make up for this weakness with more material (and weight) in places it isn't otherwise needed.

    I suppose its easy to praise one of the best free float handguards ever made. When you sit back and look at the KMR you can tell how much research and design hours they put into it. They didn't just make something that looked different from what's currently on the market. They designed something that performed better as well.

    And to add to that, their Lead Engineer, Designer did just show up and educate our asses. There was quite a bit of hypothesizing going down in this thread and the record was set straight. Tells me that they are listening, are concerned and care about the quality of their products. I'm sure there are those who may not be impressed by such a thing, but I, for one, appreciate the proactiveness.
