under the turret is a brass triangle.
Factory setting stops the turret at 0
Flip it over gives a -0.4
take it out and it can go down till turret hits. All scopes will be different here. Will not effect function.

even switching barrels, which I do alot with all these divisions and weight classes popping up, having that .4 under has been plenty. if its more than .4, its super easy to loose quick detach turret and go up to 2 mils and tighten quickly without allens. I agree tho it sure is nice having the ability to dial below zero.
