i tried the kydex riser, it works but i dont like the looks, i think it is the cheapest option
then i tried a triad stock pack, very comfortable and a pounch for documents.. until it rains.. then it sux
after that i put in KMW riser hardware, i think thats the best option, i would let someone to the work as its a pain in the @$@#% to do it clean, i think a guy called duco here on the forum does those installs very cleanly
the last option i found interesting is the Manners riser, very simple and looks clean but i havent tested that
