I notice alot of online dealers sell these under various titles, are they all of similiar quality.  I need solid info as this system will be used on all of our sniper/spotter secondary weapon platforms....standard 14.5" Colt M-4 with permanant carrying handle.  Type of glass is not set in stone yet but will probably be short to mid-range in a Larue mount.  Thanks for the help

When I scope my traditional uppers I use a Smith Enterprises Mount with Leupold PRW Rings.

The style of optic you are going to use will have a pretty important bearing on this decision. For example, Trijicon ACOG's and (I believe) Leupold CQT's are designed to mount directly into a carry handle and have adapters to be mounted to a rail. That would obviate the need for a separate carry handle mount. The ACOG's also have see thru bases for iron sight usage. I don't have any experience with the see thru carry handle mounts with the exception of the drop down style mount from Cavalry Arms which allows for a cowitness red dot sights like an aimpoint, and unfortunately I haven't had the opportunity to shoot with one. I guess the gist of my post is that at least a somewhat clearer idea of what type of optic you plan to use (i.e. red dot, magnified, variable magnification, etc) will be helpful in determining which mount will suit your purposes best.
