    Rails don't go through 1/10th of the forces, streses, and loads that any of those products do.

    Using some new alloy and jacking the price up, is a waste of money, IMO. Unless it shaves off like 6-8oz, there is no value in it.

    Goes right up there with CHF barrels, and all the idiot masses who eat that shit up like its some kind of superior method of barrel creation (when in fact, its the cheapest).

    When normal rails start breaking from the abuse (DD, Noveske, Larue,ect), let me know. I have yet to see it.

    So your saying the new BCM rail would definetly be worth it no matter the price comsidering a larue 13.2" rail is 17.8oz and the BCM 13" has been mentioned here to possibly be 7.7oz? That's way over your arbitrary 6-8oz reduction.

    ETA more rail porn

    I really like the rail and everything BCM makes is gold. That optic though.....worste $850 I ever spent.

    My point was that an alloy exists that will easily serve as a material to manufacture a durable rail from. The poster I quoted expressed concerns that a magnesium alloy would lack durability.

    Goes right up there with CHF barrels, and all the idiot masses who eat that shit up like its some kind of superior method of barrel creation (when in fact, its the cheapest).
    The process reportedly creates a more durable barrel but really is over-rated IMO. A quality honed button rifled barrel is as accurate as any CHF barrel from what I have seen. As far as "the masses" are concerned.. its the same mentality as paying twice the price for a rollmark ... or worshiping a weapon platform.

    Anyhow different subjects for a different thread.... lets try to stay on topic

    I dont think this has been a problem, or will be.

    Why, out of curiosity? I have been considering one.

    i really like mine, better field of view than a t1, better battery life than an eotech. has a solid mount, uses AA batteries, and has a 1.75 moa dot

    Has reflection problems, whether it be seeing your own face or seeing 2 dots.

    Magnesium is very, very light.

    Pure aluminum weighs 2712 kg per cubic meter.
    6061 aluminum weighs 2720 kg per cubic meter.
    7075 aluminum weighs 2800 kg per cubic meter.
    Pure magnesium weighs 1738 kg per cubic meter.

    Magnesium is roughly thirty six percent lighter by volume than aluminum. 473 degrees celsius to ignite Mg ribbon...much higher for larger samples. In fact it has been used in high performance engines for a long time.

    I'm not really on the keymod bandwagon, but Mg alloys are a damn good choice for rails.

    Just a note, it's not "reportedly." The science is there, hammer forged barrels are in fact more durable. It's not up for debate...forging has been proven to provide the benefits claimed. The fact that the barrels are produced faster, more consistently, and more inexpensively(if you don't count the cost of the forge,) are icing on the cake. What can be debated is whether or not it matters to 99% of shooters...of course it probably does not.

    Just a missed opportunity with some bad fleas.

    First is the price. Its $450 more than a PRO but offers the same battery life and a .25moa smaller dot.

    The solar panel does not power the optic if the battery is dead, it only works if the battery dies while in the sun. This was a huge missed opportunity and really came out with me questioning why is it even there if it only works when you have a good battery.

    There is a horrible reflection from the diode set in the optic that completely blocks your target and minimizes the dot enough that you cannot see it.

    Its heavier than other optics.

    The only pros imo was the large FOV and the Bobro mount.
