This product is often advertised for an offset mount on a gun with side rails. It serves its purpose well there, however, I purchased this to use with an AUG A2, that has no side rails. This works well as the AUG A2 only has a top rail only suitable for sights. The is a clever piece to get around that as you can attach it on top and still have a light or laser mounted 45 deg. to the side, and it still wont obstruct the view of the red dot mounted on top!
I've also tried this on my friends SCAR, and it still serves its purpose there.
May seem like a pointless accessory for a typical M4 or gun with side rails, but for those still trying to keep the AUG franchise alive, this is a great tool.
Great for its purpose listed and a 45 deg. mount
Works for those who want extra accessories on an AUG
Metal, good quality feel
Universal rail fit
May be a bit pricey for its size/ purpose
