    Some very interesting and valid commentary. Overall it seems to have no merit. Thanks for the info. FWIW/FYI many chainsaw body casings are made of magnesium allow. I haven't scene any burn up yet. I'll have to see if I can get an old parts saw to set alight.

    Big difference in pure magnesium and magnesium/aluminum/zinc alloys. You can weld most magnesium alloys, so I don't they present much fire danger in an AR application....or a chainsaw.

    Magnesium AR lower

    I have no idea if the specific product is any good, but I don't get all the negativity around something different because it is different. Aluminum is nice, but it isn't the only material with merit. The talk about magnesium being a fire hazard is just silly. Magnesium can be both light and strong as can titanium. Would they make a good lower? Dunno, but I certainly wouldn't dismiss it out of hand. Certainly not because aluminum is "good enough" and we should stop making things better because we already have good enough.

    Don't forget mfg process and heat treatment can make a huge difference even with the same material as well.

    Do you harbor this kind of vitriol for those that carry polymer framed handguns? Alloy J frames?

    Re: Magnesium AR lower

    Someone should go tell the auto industry about the downsides of magnesium. After all, there starting to manufacture key structural components out of it to decrease weight for fuel economy. Magnesium is stronger than aluminum and thus you can make a part thinner thus lighter. Yes it's flammable but only in certain conditions. It's extremely ****ing hard to light in a solid form. It's not more brittle if you select the correct alloys. The reason it's not used for many things is because it's a more expensive material and aluminum usually does the job just fine for most things. If you simply machine a lower out of it it will weigh about the same. To make it lighter you would have to re engineer it to use less material and to take advantage of magnesiums higher strength. Some of you guys really need to learn about it before dogging on magnesium. If the right alloy was used I'd prefer a standard lower made from it, if it was well engineered I wouldn't mind the weight savings but markm is right. If you can't handle the aluminum lower in 90% of situations then your a ****ing puss!

    ...and let's all not forget what thermite is: Aluminum and iron oxide - two components I'm certain that are present in most ARs.
