So far it's about two years old and looks new. I only polished it once with some old polishing cloth I had for magnesium wheels. Some of you are probably too young to remember when aftermarket wheels were available in bare magnesium. it's on an upper shooting corrosive ammo (7N6) so it gets a regular bath in hot soapy water.

Full disclosure, magnesium isn't as strong as aluminum. There are some pics of broken magnesium receivers out there. And the weight difference is negligible. But for a range toy, it works. So if this is the look you're going for, it's a cheap option that doesn't appear to need much maintenance.
Saying that magnesium isn't as strong as aluminum isn't fair. Saying the poorly poured Mag Tactical lower is not near as strong as an aluminum forged mil spec lower would be fair.
