just a heads up i called larue and spoke w/ my buddy who works there. they said it not on their website yet but it is for sale and will fit a uso w/ tpal. according to him its got almost 3 inches between the rings. i will take some pics when it gets here. hopefully it all works out as this is how i wanted the set up to be. just a heads up for anyone who might have been looking like i was. just figured i would throw this out there.
