JL Progression Amphibious Red Dot Sight Mount for Hi-Capa - Red
The best mount you can currently buy for Red dot Sights.
Made from machined aluminium and precisely cut to fit Hi-Capas perfectly.
Comes with every possible screw need to mount a range of Red dot sights.
It is advised you drill and tap the frame but after fitting one on to my personal Capa, its solid.
