I bought one of those scopes just to see if it actually worked well,and it does.I have it on one of my AR15's - a 223. A 308 is about the biggest calibers that I'd trust this scope on.
From the testing that I've done on mine,it works fine,nothing to brag about. The glass is decent,it tracks good so far,and it repeats zero so far.
For $230,it's a decent deal,and by far the cheapest/best quality FFP scope out there.
