Changed my mind, went back and upgraded to the Larue Tactical combo upper :). Decided I didn't have to have a KMR rail I've already got one so got something different for this one.
They also happened to have a LWRC M6IC lower in the store, fully kitted out. So I grabbed that while I was there as well. Been looking for a fully ambi lower (ie, ambi bolt lock AND release) for a while now but they are few and far between... KA, LWRC, the AXTS I think is all really... Was surprised they had one actually.
