Just happened to come across this on the Brownells website http://www.brownells.com/rifle-parts...13?ICID=300080. Does this have any practical applications or is this a gimmick? With all the accessories being put on modern AR's, dropping a little weight can't hurt. Remington is using Magnesium for the lowers on their ACR's. What do you guys think?

Some guy on TOS had a case head separation and it blew a huge hole in his Mag Tac lower.
Maybe a forged lower would have done the same thing (I dont think it would have), but I dont feel the weight savings is worth it.

Got a link?

FYI, I dont agree with the OP who thinks the manufacturer should refund all his money for the 10 lowers he bought.
He knew they weren't the standard forged aluminum and he bought them anyway.
He claims that because the manufacturer stated they are "just as strong" that he should be able to send all 10 back.
Its like trying to get a refund on a polymer lower because it turns out its not as strong as forged aluminum.

Interested, I went to their web page and looked around.
I found a really pathetic page with almost no information, and rapidly lost interest.

Why even bother with shit like that.
Besides, isn't magnesium potentially a flammable hazard?

If you can get it to light. Hint: You're going to need a torch.Originally Posted by rojocorsa

Stupid.
Manganese is brittle, and will burn hot as **** if it catches.
Some people will always waste their money.

I'm assuming you meant magnesium as manganese is an entirely different element. Autocorrect?
Sorry to nitpick, but might as well be accurate. A manganese lower wouldn't be very lightweight, it's more than double the density of aluminum, let alone magnesium.
Magnesium-vs-Manganese
Hell, even if you made everything out of magnesium that is normally aluminum your weight savings wouldn't be that substantial if most of the weight is coming from the steel barrel anyway.

I'm not cool. I just do this stuff for fun.

The transmission and engine block in three of my cars are magnesium. I don't think you'll have to worry about spontaneous combustion.
