So I have a lead on one of these scopes, but it has the capped turrets. I realize the rarity of this item in ANY configuration right now, and dont think this will be enough to deter me from procuring it, but I would like some input from guys who have run the capped turrets and how much of an annoyance they are to running this scope. BTW this will be going on an 18" barreled SPR.
