Note: blue loc tite should be applied to the screw that screws into the blowback unit. The LA Capa Customs Lightweight 5.1 Fiber Optic Rear Sight is the perfect addition for any 5.1 build! The special cutouts and aluminum build make this rear sight extremely lightweight!
In addition to side trapezoids to fit snugly into your slide, this rear sight also has a screw that screws into the blowback unit, keeping it even more secure. This rear sight comes in 12 different colors and both red and green fiber optics!
