Whats the difference

What is different between the 7065 lower and the 5165500387? Those are the SKU numbers. For some reason i cant post the links. The 7065 lower doesnt offer much for description.

Any help is appreciated!!!

Looks like 7065 is a regular lower while the other is a stealth lower. Otherwise the same from ahzt i can tell.

Whats different between stealth lower and regular lower?

The stealth lower doesnt have a logo rollmark.

Thanks!!!
