Carry handle mount for rra 9mm - Leupold Mark 4 AR-15/M16 Handle Mount

I purchased this carry handle mount to mount a TRUGLO red/green dot scope on a Rock River Arsenal 9mm AR-15. It did require fitting as some some of the other reviewers also experienced. However, this resulted in a very tight, solid fit. There is absolutely no looseness or wobble as I experienced with a B-Square mount. Also, an added feature is that the iron sights are usable with the mount attached through a port that runs through the base of the mount.
Pros: Leupold quality; rock solid
Cons: May require fitting
