The Gunsmith Bros CNC Aluminum TWO TWO Open for the Tokyo Marui Hi Capa 5.1 is an amazing quality set which also comes with a charging handle for a rear sight, blowback housing with its piston, slide, compensator and guide rod. Grab yours before they're all gone. These are limited edition runs even though there are a large selection to choose from!

High precision CNC machined aircraft grade aluminum with the layout of the classic pistol with the deep serrations.

The Gunsmith Bros set has a sublimely superb finish. The slide is finished with a matte coat to alter the felt texture as well as reduce the shine to a dulled type rather then polished.

The Gunsmith Bros Aluminum TWO TWO Open is a drop in and use part that you can easily install yourself. If unsure, do consult a gun technician.
