Geissele's Super Configurable Ambidextrous Black Safety Selector is a perfect upgrade to any AR platform. The levers can be swapped and exchanged with Geissele's other levers, allowing you to find the right fit, look, and feel on your rifle. The Super Configurable Ambidextrous Black Safety Selector is held in place via retained plunger that under spring tension, keeping them securely in place and eliminating the risk of losing an attachment screw during cleaning or maintenance.
