Currently using Baer bases on this rifle. A friend in Ca. put them on and I can't seem to contact him at all. Was looking into a trajectory compensating turret and they need too know if I'm using tapered bases and 20MOA or 40MOA. Or just regular bases. Can anyone give me an opinion based on my pictures? Or maybe a contact number or website where I might possibly get the info I need? Thanks. Maybe can't tell in the last picture but, the rear base is way higher that the front.
