CAA TPR5 Top Picatinny Rail for MP5/SD/K, G3

CAA’s TPR5 clamps to HK MP5, MP5K, MP5SD and G3 receivers to give them a rigid 4″ MIL-STD-1913 top rail. The lightweight aluminum mount installs with two bolts—no gunsmithing—and keeps zero even after routine field-stripping, providing a rock-solid base for red-dot optics or other accessories.
