    These are the only details we'll be releasing at this time.
    PLEASE consider doing a .308 rail, preferably DPMS! The lightest rail I know of for a .308 AR is the Troy slick rail, and at 13.8" it's about 13oz including nut.

    For people trying to get the lightest rail they can on a .308 AR, the Troy's the only real option we have at the moment. So if something comes along that's 5oz lighter than the current lightest rail, then pretty much there'll only be one acceptable choice if you're looking for a lightweight rail without giving up any features/functionality.

    The BCM rail looks good, but there aren't many ways to configure a Keymod so I think we will see a lot which look similar. The largest differences are going to be how wide a company goes and its attachment method.
    I am way late on this but this is the first time I watched that vid and that is exactly what i did when he was going through that list. The entire time after that i was just like, I think you missed one man hah.

    Thanks
    Phreakish did report two rail lengths planned - 13 and 10. This is all the info they are willing to divulge right now.

    I am sure they are busy with finalizing the product specs and am willing to wait for them to sort things out.

    Based on the numbers alone, I am going to set aside a future build to use these rails!

    New BCM rail

    Wow, that's really light.

    I didn't realize the NSR was that light either. Been out of the rail game for too long.

    I'm really liking how this BCM rail is sounding, and I love the fact rail manufacturers are focusing on reducing weight. It makes a lot of difference in how a carbine handles.

    I didnt think it was possible to get much lighter than what the NSR offered. When I got my 13.5 rail it to me it's mass was nearly imperceptible.

    Crazy stuff technology lol

    I'll wait for a mid-length cutout version but it sure sounds good.

    4.3oz! That is about 1.8oz lighter than what a 10" NSR rail only would be (6.15oz)!
    Damn you BCM! I just permed my 14.5" Skinny Barrel 11" NSR combo.

    For those of you on lightfighter there are a couple great pics of this rail in one of Pat Roger's threads.
