Not designed well - Armaspec AR10 Gun Builders Lower Parts Kit

The color is not black so it stands out against the black lower. The take down pins require a hammer to push out which is horrible if you need to get in your gun without tools. There are sharp edges where things should be polished and smooth. For so few parts at almost 80 bucks its not worth it at all. The company didn't take their time to polish and take pride in their work. find something else.
