This DeltaPoint Pro Dovetail Mount is designed to fit a Springfield. The DP-Pro AR mount brings the red dot to the right height without adding a ton of weight or bulk. The DP-Pro Iron Sight co-witnesses with the red dot for continued functionality in the case of battery failure. 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. The DeltaPoint Pro 45-degree AR Mount allows buyer to mount a DP-Pro to any Picatinny rail for maximum versatility and extremely quick transitions between magnified optic and red dot.
