The Geissele Super Configurable AR-15 Safety Selector is a high quality, ambidextrous replacement for the mil-spec safety in your carbine. The levers are easily swappable and exchangeable with other Geissele levers to find the perfect fit, look and comfort for your desired operation. The levers are held in place by a retained plunger under spring tension, making sure they remain securely attached during hard use and mitigating the possibility of misplacing or losing an attachment screw during cleaning or servicing of your carbine. The Geissele Super Configurable Safety selector barrel is made from stainless steel, chosen for its durability and anti-corrosion properties.
