Leupold 171861: Most people think of the DeltaPoint Pro as a pistol sight, but it is just as capable on an AR platform as it is on a handgun. Our DP-Pro AR Dloc Mount puts the DeltaPoint Pro at the perfect height on your AR platform. The Dloc allows you to quickly detach and reattach from your firearm. The DP-Pro mount adapter can be used on any Picatinny, Weaver, or cantilever rail or base that doesn\'t require a riser, while the DP-Pro riser can be used on flat-top AR rifles with Picatinny rails.
