Ooooooooo ahhhhhhhhhh, I just saw that you have that top one ready for a can!!!!
Yuuup. Got a YHM Ti 308 for it.
if you like the way the ultimak rail looks extending all the way forward, Midwest industries also makes one that does the same thing.
This is the version that allows you to add rail where you want it.
I think samson makes a rail that goes the full length, but it's kinda odd. Your best options are ultimak or MI.
