I have a Primary Arms micro dot the detachable base model. Comes with original base and Daniel Defense riser mount. I also have off set weaver rail mount for the micro dot as seen in first picture this allows you to mount it off set from primary magnified optics to quick switch between close and far shots.
Asking $140 shipped add offset mount for $20
Only trades would be a TRL1, flash lights, or knives depending on trade will need cash to make up difference
This set comes with Micro Dot, DD mount with box, and PA low base.
