KAC URX II Medium vs DD MK 18 RIS II

[elanaiba]

What is the length difference between the medium size KAC URX II and the Daniel Defense RIS II ?

I know the URXII is about 1" longer, but what about the lower rail - is it longer? Specifically, if I'd want to push a Magpul AFG 1 rail space further out, would the URX II help vs the RIS II ?

The KAC URX II is longer than the DD MK18 RIS II on the bottom rail, as well as the other sections.

Ok, thanks for the help!

No problem, figure that you probably pick up 3/4" or an inch of extra space the KAC rail.
