Gun Disassembly via Mac

[ToddG]

Apologies if it's been mentioned elsewhere and I missed it, but:
Gun Disassembly 2 v1 for Mac
It's a free app that allows you to operate, disassemble, and reassemble various weapons as well as watch them go through their cycle of fire with various degrees of "x-ray vision." It's pretty fascinating.

If this is the same one on the iPad, I noticed a number of errors on the guns. I can't list them because I uninstalled it.

I am not sure if it works for Mac, but for Sig's the Sig Armorers DVDs have a similar 3D xray vision effect. And since it is made by Sig it is much more accurate.
