Does anyone have a particular brand of sights that they like? NECG has been recommended to me. They don't seem to offer a nice fixed V sight though.

They have two fixed rear sights that look pretty nice.
One is called a

Forward Slanting Fixed Rear Sight
Width: .708"---Length: .630"---Overall height: .630"

The other is called a

Straight Fixed Rear sight
Width: .708"---Length: .630"---Overall height: .630"

Why the slant vs straight?

Thanks
Pat
